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 and cooked through, approximately 6-8 minutes. Drain excess fat if necessary.
02 - Sprinkle chili powder, cumin, smoked paprika, garlic powder, onion powder, salt, and black pepper evenly over the meat. Stir thoroughly to distribute spices and continue cooking until fragrant.
03 - While the meat cooks, wash and chop romaine lettuce into bite-sized pieces. Halve cherry tomatoes, thinly slice red onion, dice cucumber, and cube avocado.
04 - If using cauliflower rice for extra volume, microwave according to package directions or sauté in a separate pan until heated through.
05 - Create a base layer with chopped lettuce and warmed cauliflower rice. Arrange seasoned meat, tomatoes, cucumber, red onion, and avocado on top in sections.
06 - Garnish with shredded cheddar cheese, a dollop of sour cream, fresh cilantro, and a spoonful of salsa. Serve with lime wedges for squeezing over the bowl.
