Whether it’s a weeknight dinner, meal prep for the week, or a healthy lunch, this bowl delivers bold Mexican-inspired flavors while keeping your meals nutritious and filling.

The Inspiration Behind the Recipe

Fajitas are a classic Tex-Mex favorite, known for their sizzling steak and vibrant peppers. Traditional fajitas often come with tortillas, rice, or high-calorie toppings. Here, we’ve reimagined the classic fajita as a lean, high-protein bowl:

  • Lean steak provides quality protein for muscle recovery and satiety.
  • Bell peppers and onions add color, fiber, and natural sweetness.
  • Avocado and cilantro provide healthy fats and freshness.
  • Lime juice and spices elevate the flavor profile without adding unnecessary carbs or calories.

This recipe is perfect for anyone wanting the taste of fajitas without the extra starches — it’s clean, healthy, and incredibly satisfying.

  3. Vitamins & Minerals: Bell peppers are high in vitamin C, onions provide antioxidants, and avocado adds potassium and healthy monounsaturated fats.
  4. Anti-Inflammatory Spices: Paprika, cumin, and chili powder bring flavor while supporting digestion and inflammation reduction.
  5. Fiber-Rich: Vegetables and avocado increase fiber intake, aiding digestion and satiety.
