Place a large skillet over medium-high heat and add the ground beef, breaking it apart with a spatula.
Cook the beef until fully browned and no longer pink, about 7-8 minutes, then drain any excess fat if necessary.
Stir in the chili powder, cumin, garlic powder, and sea salt until the meat is evenly coated and fragrant.
Wash and chop the romaine lettuce into bite-sized pieces and place them in a large serving bowl.
Halve the cherry tomatoes, dice the bell pepper, and finely mince the red onion.
Top the lettuce with the warm seasoned ground beef and the prepared fresh vegetables.
Slice the avocado and place it on top of the salad.
Finish the bowl by adding the salsa, drizzling with lime juice, and garnishing with fresh cilantro.
