Carne Asada Street Tacos:
A Protein-Rich Meal for Strength
Carne Asada Street Tacos prove that a meal can be flavorful, satisfying, and supportive of your strength-training goals without being complicated.
Made with lean flank steak, stone-ground corn tortillas, feta cheese, red onion, salsa, cilantro, and fresh lime, these tacos provide an impressive balance of protein, carbohydrates, fiber, healthy fats, vitamins, and minerals.
Each two-taco serving provides approximately 38 grams of protein, making this an excellent meal for women over 65 who are working to maintain or rebuild muscle through strength training.
Why Protein Matters More as We Age
Muscle mass and strength naturally become more difficult to maintain as we age. The decline in muscle power and physical performance tends to accelerate after approximately age 65 in women, making strength training and supportive nutrition especially important.
Strength training gives your muscles the stimulus they need to become stronger. Protein supplies the amino acids your body uses to repair and rebuild the muscle tissue challenged during exercise.
This does not mean you need to live on protein shakes or eat the same plain chicken breast every day. Protein can come from enjoyable, well-balanced meals like these carne asada street tacos.
With about 38 grams of protein per serving, this recipe can work especially well as:
- A satisfying meal following a strength-training workout
- A protein-rich lunch on an active day
- A flavorful dinner that supports muscle maintenance
- A healthier alternative to many restaurant-style tacos

The Strength-Supporting Benefits of the Ingredients
Flank Steak: Lean Protein for Muscle Repair
Flank steak is the primary protein source in this recipe. A four-ounce portion helps provide the amino acids needed for muscle maintenance, repair, and recovery.
Beef is also a source of several nutrients that support an active body, including:
Iron: Iron is needed to make hemoglobin, which carries oxygen through the blood, and myoglobin, which supplies oxygen to muscles. It also supports normal muscle metabolism.
Zinc: Zinc participates in protein synthesis, cell repair, immune function, and wound healing.
Vitamin B12: Vitamin B12 supports healthy red blood cells and normal nerve function.
Because flank steak is relatively lean, slicing it thinly across the grain is important. This shortens the muscle fibers and makes the meat more tender.
Corn Tortillas: Carbohydrates for Training Energy
The corn tortillas provide carbohydrates, which are one of the body’s main sources of energy.
Protein may receive most of the attention in a strength-focused meal, but carbohydrates also have an important job. They help fuel activity and replenish some of the energy used during exercise.
Stone-ground corn tortillas also provide more fiber and texture than many highly refined flour tortillas. Using smaller five- to six-inch tortillas helps keep the portion manageable while still creating a satisfying meal.
Feta Cheese: Additional Protein and Calcium
Feta cheese adds a salty, tangy flavor along with a modest amount of protein and less fat than queso fresco.
It also contributes calcium, which is important for:
- Maintaining strong bones
- Supporting normal muscle contraction
- Helping nerves communicate with muscles
- Supporting normal heart function
You may use regular or reduced-fat feta depending on your nutritional needs and flavor preference.
Although feta is not a traditional Mexican taco cheese, its crumbly texture and slightly salty flavor make it a practical substitute for queso fresco.
Red Onion: Flavor, Texture, and Plant Nutrients
Red onion adds crunch and a slightly sharp flavor that balances the richness of the beef and cheese.
Onions contain vitamin C and a variety of naturally occurring plant compounds. Vitamin C helps the body produce collagen; a structural protein used in connective tissue, and also functions as an antioxidant.
If raw onion tastes too strong, soak the sliced onion in cold water for approximately 10 minutes and drain it well before serving.
Salsa Verde or Tomato Salsa: Vegetables Without Heaviness
Salsa adds moisture and flavor without requiring a heavy sauce.
Depending on the ingredients, salsa may provide tomatillos, tomatoes, peppers, onions, garlic, cilantro, and lime. These ingredients add vitamin C and protective plant compounds while contributing relatively few calories.
Choose a salsa with the heat level that works for you. A mild salsa verde is an excellent choice when you want fresh flavor without excessive spice.
Cilantro: Fresh Flavor with Very Few Calories
Fresh cilantro brightens the finished tacos and complements the garlic, oregano, onion, and lime.
Although cilantro is generally eaten in small quantities, it adds flavor without relying on additional fat or salt. It is optional for anyone who does not enjoy its distinctive taste.
Fresh Lime: Flavor and Vitamin C
A squeeze of fresh lime brings all the taco flavors together.
Lime juice provides vitamin C, which the body uses in collagen production and protein metabolism. Collagen is an important part of connective tissues such as skin, tendons, and ligaments.
The acidity of lime also allows you to add brightness and intensity without adding more salt.
Garlic: Big Flavor in a Small Amount
Fresh garlic is pressed into the surface of the steak so its flavor becomes part of the meat rather than simply sitting on top.
Garlic contains sulfur-containing plant compounds and makes it easier to create a deeply flavored meal without relying on rich sauces.
Extra-Virgin Olive Oil: A Small Amount of Healthy Fat
Only a small amount of olive oil is needed to help the steak brown and prevent sticking.
Olive oil primarily provides monounsaturated fat. Using it sparingly gives the recipe the cooking benefits of oil without overwhelming the meal with added fat.
Mexican Oregano: Earthy Flavor Without Added Calories
Mexican oregano comes from a different plant family than Mediterranean oregano. It has a more earthy, woodsy flavor with subtle citrus notes that work especially well with beef, chilies, beans, and salsa.
It may be found in the Latino foods section, spice section, or produce area of many larger grocery stores.
Crema Mexicana: Optional Richness
Crema Mexicana adds richness and helps soften the heat of spicy salsa.
Because it contributes additional calories and saturated fat, it’s best used as an optional finishing ingredient. A small drizzle is usually enough.
A More Balanced Alternative to Traditional Restaurant Tacos
This FemStrength65 version uses flank steak, corn tortillas, measured cheese, salsa, and an optional small amount of Crema Mexicana.
Based on the recipe’s nutritional calculation, one serving of two tacos contains approximately:
- 365 calories
- 38 grams protein
- 24 grams carbohydrate
- 5.6 grams fiber
- 11 grams fat
- 95 milligrams cholesterol
- 563 milligrams sodium
The traditional comparison made with skirt steak, flour tortillas, additional cheese, and sour cream contains approximately:
- 750 calories
- 45 grams protein
- 56 grams carbohydrate
- 2 grams fiber
- 39 grams fat
- 101 milligrams cholesterol
- 1,368 milligrams sodium
The lighter version still provides substantial protein while significantly reducing the calories, fat, and sodium.
Cook’s Notes
For more tender steak: Always slice flank steak thinly and across the grain. Cutting with the grain leaves the long muscle fibers intact and makes the meat seem tougher. See illustration:
For easier preparation: Season the steak the night before, slice the onions, and prepare or purchase the salsa
in advance.
For more protein: Serve the tacos with black or pinto beans.
Strength Starts With What You Do Consistently
No single meal builds muscle by itself.
Strength develops through consistent resistance training, adequate recovery, and regular meals that provide the protein and energy your body needs.
These Carne Asada Street Tacos offer an enjoyable way to support that process. They provide plenty of protein, useful carbohydrates, satisfying flavor, and a variety of nutrients in a meal that does not feel like “diet food.”
Eating for strength after 65 should still be something you enjoy.
