Ingredients
Method
- Prep the chicken and veggies: Slice chicken into thin strips. Slice peppers and onion. Mince garlic. This helps everything cook quickly and evenly.
- Mix the spice blend: In a small bowl, combine chili powder, cumin, smoked paprika, oregano, cayenne, 1 teaspoon salt, and 1/2 teaspoon black pepper.
- Season the chicken: Toss the chicken with half the spice blend, half the minced garlic, 1 tablespoon oil, and the zest of half a lime. Set aside while you heat the pan.
- Sear the chicken: Heat a large skillet over medium-high with 1 tablespoon oil. Add the chicken in a single layer. Cook 5–7 minutes, stirring once or twice, until browned and cooked through. Transfer to a plate.
- Sauté peppers and onions: Add another 1 tablespoon oil to the same skillet. Add peppers and onion with a pinch of salt. Cook 5–6 minutes until tender-crisp with some char. Add remaining garlic and the rest of the spice blend. Stir 30–60 seconds until fragrant.
- Bring it together: Return chicken to the skillet. Squeeze in the juice of half a lime. Toss to coat. Taste and adjust salt, pepper, or lime as needed. Sprinkle with chopped cilantro.
- Cook the cauliflower rice: In a separate pan, heat a teaspoon of oil over medium. Add cauliflower rice with a pinch of salt and pepper. Cook 4–5 minutes until hot and just tender. Squeeze in a little lime juice if you like.
- Assemble the bowls: Spoon cauliflower rice into bowls. Top with the chicken and veggies. Add your favorite toppings: avocado, sour cream, cheese, pico, jalapeños, and extra cilantro.

Why This is Good for You
- Low in carbs, high in flavor: Skipping tortillas and rice helps keep net carbs down without feeling deprived.
- Protein-packed: Chicken supports muscle repair and keeps you fuller for longer.
- Fiber and antioxidants: Bell peppers and onions add vitamins A and C, plus fiber for digestion.
- Healthy fats: Avocado and olive oil provide satiating fats that fit a keto lifestyle.
- Steady energy: Balanced macros can help curb cravings and support stable energy levels.
What Not to Do
- Don’t overcrowd the pan: Crowding steams the chicken and peppers instead of giving them that tasty sear.
- Don’t skip the salt and acid: Proper seasoning and a squeeze of lime make the flavors pop.
- Don’t overcook the veggies: Mushy peppers lose their sweetness and crunch.
Aim for tender-crisp.
- Don’t rely on sugary sauces: Many store-bought fajita or taco sauces contain hidden sugars. Stick with spices and lime.
- Don’t store with wet toppings: Keep salsa, avocado, and sour cream separate to prevent soggy leftovers.
Recipe Variations
- Spicy chipotle: Add 1–2 teaspoons chipotle paste or chopped chipotle in adobo to the chicken for smoky heat.
- Steak or shrimp: Swap chicken for skirt steak (cook hot and fast, slice thin) or shrimp (cook 2–3 minutes). Adjust timing accordingly.
- Dairy-free: Skip cheese and sour cream.
Use avocado crema made with coconut yogurt and lime.
- Extra veggies: Toss in mushrooms or zucchini for more volume with minimal carbs. Sauté briefly to avoid sogginess.
- Cheesy cauliflower base: Stir shredded cheddar or pepper jack into the hot cauliflower rice for a melty, comforting base.
- Bowl to salad: Serve the fajita mix over a big bed of romaine with avocado and a lime-cilantro dressing.
