01 - Toss chicken pieces with olive oil, chili powder, cumin, smoked paprika, garlic powder, salt, and black pepper in a mixing bowl until evenly coated.
02 - Heat a large skillet over medium-high heat. Add the seasoned chicken and cook for 6-8 minutes, stirring occasionally, until fully cooked and lightly browned. Transfer to a plate and cover to keep warm.
03 - In the same skillet, add 1 tablespoon olive oil and the riced cauliflower. Cook for 4-5 minutes, stirring frequently, until tender but not mushy. Season lightly with salt and pepper.
04 - Dice the bell pepper and red onion, halve the cherry tomatoes, slice the avocado, and chop the fresh cilantro.
05 - Create each bowl with a base of riced cauliflower. Layer with cooked chicken, bell pepper, onion, tomatoes, avocado, cheese, and salsa. Top with sour cream and jalapeño slices if desired. Garnish with fresh cilantro and serve with lime wedges.
06 - Serve the burrito bowls while the chicken and cauliflower rice are still warm for the best texture and flavor.
