Ingredients

  

• For the chicken and veggies: 1.5 pounds boneless, skinless chicken breasts or thighs, thinly sliced
• 1 red bell pepper, thinly sliced
• 1 green bell pepper, thinly sliced
• 1 small yellow onion, thinly sliced
• 2 tablespoons avocado oil or olive oil, divided
• 1 tablespoon fresh lime juice
• Fajita seasoning mix: 1.5 teaspoons chili powder
• 1 teaspoon ground cumin
• 1 teaspoon smoked paprika
• 1/2 teaspoon garlic powder
• 1/2 teaspoon onion powder
• 1/4 teaspoon dried oregano
• 1/4–1/2 teaspoon crushed red pepper flakes (optional, for heat)
• 3/4 teaspoon fine sea salt, plus more to taste
• 1/4 teaspoon black pepper
• For the bowls: 4 cups shredded romaine or iceberg lettuce or 3–4 cups cooked cauliflower rice
• 1 medium avocado, sliced or cubed
• 1/3 cup sour cream or Greek yogurt (lower carb if unsweetened)
• 1/2 cup shredded cheddar, Monterey Jack, or pepper jack
• Fresh cilantro, chopped
• Lime wedges
• Sugar-free salsa or pico de gallo (check labels)

Method

 

1. Prep the chicken: Pat the chicken dry and slice into thin strips. This helps it cook fast and stay tender.
2. Mix the seasoning: In a small bowl, combine chili powder, cumin, smoked paprika, garlic powder, onion powder, oregano, red pepper flakes (if using), salt, and black pepper.
3. Season the chicken: Toss the chicken with half the seasoning and 1 tablespoon of oil until well coated.
4. Sear the chicken: Heat a large skillet over medium-high. Add the chicken in a single layer. Cook 5–7 minutes, stirring once or twice, until cooked through with some browned edges. Transfer to a plate.
5. Cook the veggies: In the same skillet, add the remaining 1 tablespoon oil. Add the peppers and onion, sprinkle with the rest of the seasoning, and sauté 5–7 minutes until tender-crisp with some char.
6. Combine and finish: Return the chicken to the skillet. Add lime juice and toss for 1 minute to warm through and brighten the flavors. Taste and adjust salt or heat.
7. Assemble the bowls: Add lettuce or cauliflower rice to each bowl. Top with the chicken and fajita veggies.
8. Add toppings: Finish with avocado, cheese, sour cream or yogurt, cilantro, a squeeze of lime, and a spoon of sugar-free salsa.
9. Serve: Enjoy warm. Add extra lime or hot sauce if you like it zesty.

Storage Instructions

• Refrigerator: Store chicken and veggies in an airtight container for 3–4 days. Keep toppings like avocado, lettuce, and salsa separate to prevent sogginess.
• Freezer: The cooked chicken and peppers freeze well for up to 2 months.

  Cool completely, portion, and freeze. Thaw overnight in the fridge and reheat in a skillet.

• Reheating: Warm gently in a skillet over medium heat with a splash of oil or water to keep it juicy. Microwave works in a pinch, 60–90 seconds, stirring halfway.
• Meal prep tip: Use divided containers: base in one section, hot proteins in another, and cold toppings packaged separately.

Health Benefits

• Low carb, high satisfaction: Skipping tortillas slashes carbs while keeping the flavors that make fajitas craveable.
• Protein-forward: Chicken provides essential amino acids to support muscle maintenance and satiety.
• Healthy fats: Avocado and olive or avocado oil add monounsaturated fats, which help with fullness and flavor.
• Micronutrient boost: Bell peppers are rich in vitamin C and antioxidants.

  Onions add prebiotic fibers for gut health.

• Fiber from low-carb veggies: Lettuce and cauliflower rice help digestion and balance the meal.

Pitfalls to Watch Out For

• Hidden sugars: Some store-bought fajita seasonings and salsas contain added sugar or starch. Read labels carefully.
• Overcrowding the skillet: Too much chicken at once steams instead of sears. Cook in batches for browned, flavorful edges.
• Overcooking chicken: Thin strips cook fast.

  Pull them as soon as they’re no longer pink to avoid dryness.

• Watery bowls: Add lime at the end, not during the sear, and drain any excess moisture before assembling.
• Carb creep: Beans, corn, and tortilla chips are tasty but add up. Keep them out or use very small amounts if you’re strict keto.
