Ingredients

  

• For the chicken and marinade: 1.5 pounds boneless, skinless chicken breasts (or thighs), thinly sliced
• 2 tablespoons olive oil
• 1 tablespoon fresh lime juice (plus more for serving)
• 2 teaspoons chili powder
• 1 teaspoon ground cumin
• 1 teaspoon smoked paprika
• 1/2 teaspoon garlic powder
• 1/2 teaspoon onion powder
• 1/2 teaspoon dried oregano
• 1/2 teaspoon kosher salt
• 1/4 teaspoon black pepper
• Optional: 1/4 teaspoon crushed red pepper flakes for heat
• For the veggies: 1 red bell pepper, thinly sliced
• 1 yellow or orange bell pepper, thinly sliced
• 1 green bell pepper, thinly sliced
• 1 medium red onion, thinly sliced
• 1 tablespoon olive oil
• Pinch of salt
• For the base and toppings: 4 cups cauliflower rice (store-bought or homemade)
• 1 tablespoon olive oil or butter for sautéing the rice
• 1 avocado, sliced or diced
• Fresh cilantro, chopped
• Lime wedges
• Optional: sliced jalapeño, sour cream or Greek yogurt, salsa, shredded cheese

Method

 

1. Marinate the chicken: In a bowl, whisk olive oil, lime juice, chili powder, cumin, smoked paprika, garlic powder, onion powder, oregano, salt, pepper, and red pepper flakes if using. Add sliced chicken and toss to coat. Let it sit for 15–30 minutes (or up to 8 hours in the fridge).
2. Cook the veggies: Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add peppers and red onion with a pinch of salt. Cook 6–8 minutes, stirring occasionally, until tender-crisp with a little char. Transfer to a plate.
3. Sear the chicken: In the same skillet, add the marinated chicken in a single layer. Don’t overcrowd; cook in batches if needed. Sear 4–6 minutes, stirring once or twice, until cooked through and lightly caramelized.
4. Finish the skillet: Return veggies to the pan with the chicken. Toss for 1–2 minutes so flavors mingle. Squeeze in a bit of lime juice for brightness. Taste and adjust salt if needed.
5. Cook the cauliflower rice: In a separate skillet, heat 1 tablespoon olive oil or butter over medium heat. Add cauliflower rice and a pinch of salt. Sauté 4–5 minutes until hot and slightly tender, but not mushy.
6. Assemble the bowls: Divide cauliflower rice between bowls. Top with chicken and veggies. Add avocado, cilantro, and any extras like jalapeño, salsa, or a dollop of sour cream. Serve with lime wedges.

Keeping It Fresh

• Store components separately: Keep chicken/veggies, cauliflower rice, and toppings in separate containers. This keeps textures spot on.
• Fridge life: Chicken and veggies last about 3–4 days.

  Cauliflower rice keeps 3 days. Avocado is best cut fresh.

• Reheating tips: Rewarm chicken and veggies in a skillet over medium heat to revive char and prevent sogginess. Add a splash of water if needed.
• Meal prep hack: Portion chicken and veggies into containers with lime wedges and a baggie of cilantro.

  Pack avocado separately.

Why This is Good for You

• High in protein: Chicken helps keep you full and supports muscle repair.
• Low in carbs, high in fiber: Cauliflower rice and peppers deliver volume and fiber without the starch.
• Healthy fats: Olive oil and avocado add satisfying fats that support steady energy.
• Micronutrient-rich: Bell peppers bring vitamin C and antioxidants; herbs and spices add beneficial plant compounds.

Pitfalls to Watch Out For

• Overcrowding the pan: This steams the chicken and kills the sear. Cook in batches for best caramelization.
• Overcooking cauliflower rice: It goes mushy fast. Pull it while it’s still slightly firm.
• Too salty too soon: Some chili powders contain salt.

  Taste before adding extra.

• Heavy-handed toppings: Cheese, sour cream, and guac add up. Keep portions mindful if you’re tracking macros.

Variations You Can Try

• Sheet pan version: Toss chicken and veggies with oil and spices on a sheet pan. Roast at 425°F (220°C) for 18–22 minutes, stirring once.
• Grilled fajita bowls: Thread chicken and peppers on skewers or use a grill basket.

  Char over medium-high heat for smoky flavor.

• Spicy chipotle twist: Add 1 minced chipotle in adobo to the marinade for a deep, smoky kick.
• Mexican cauliflower rice: Sauté the rice with tomato paste, cumin, and a pinch of oregano for extra flavor.
• Dairy-free creamy finish: Stir in a spoonful of dairy-free yogurt mixed with lime and cilantro.
• Protein swap: Try shrimp (cooks in 3–4 minutes), steak, or tofu for variety.
• Bowl base switch: Use shredded romaine or a spring mix for a fajita salad vibe.

FAQ

Can I use pre-cooked chicken?

Yes. Warm it in the skillet with a little oil and the spice blend to re-season. It won’t sear quite the same, but it still works for quick meals.

Is this recipe keto-friendly?

It can be.

Keep toppings like salsa and onions in moderate amounts, go easy on tomatoes, and choose full-fat sour cream or avocado for fats. The base of cauliflower rice supports keto goals.

How spicy is it?

As written, it’s mild to medium. Skip red pepper flakes for mild, or add jalapeño, chipotle, or extra chili powder for more heat.

Can I make it without a lot of oil?

Yes.

Use a nonstick skillet and reduce oil by half. Just watch for sticking and avoid high heat that could scorch the spices.

What’s the best way to slice the chicken?

Slice it thin, across the grain, into 1/2-inch strips. Thinner strips cook fast and stay tender.

Can I freeze it?

Freeze the cooked chicken and veggies, not the cauliflower rice.

Thaw overnight in the fridge and reheat in a skillet. Make fresh rice for the best texture.

What if I don’t have cauliflower rice?

Use shredded cabbage quickly sautéed with a little oil and lime, or serve over a bed of mixed greens. Both keep carbs low and add crunch.
