01 - Heat olive oil in a large skillet over medium heat. Add ground beef or chicken, breaking it apart with a spoon. Cook until browned throughout, approximately 6-8 minutes. Drain excess fat if necessary.
02 - Sprinkle chili powder, cumin, smoked paprika, garlic powder, onion powder, salt, and black pepper over the meat. Stir thoroughly to distribute spices evenly and continue cooking until fragrant.
03 - While the meat cooks, wash and chop romaine lettuce into bite-sized pieces. Halve the cherry tomatoes, thinly slice the red onion, and dice the cucumber and avocado.
04 - If using cauliflower rice for added bulk, microwave according to package directions or sauté in a separate pan until heated through.
05 - Create a base layer with chopped lettuce and cauliflower rice (if using). Arrange the seasoned meat on top, then add tomatoes, cucumber, red onion, and avocado in sections around the bowl.
06 - Sprinkle shredded cheddar cheese over the warm ingredients. Top with a dollop of sour cream, a generous spoonful of salsa, and fresh cilantro. Garnish with a lime wedge for squeezing before serving.
