Heat a skillet over medium heat. Add ground beef and cook, breaking up with a spoon, until browned and cooked through, about 8 minutes.
Drain excess fat and stir in taco seasoning. Cook for 2 more minutes until beef is well coated and fragrant. Remove from heat.
In a wide shallow bowl, layer the chopped romaine lettuce as the base.
Arrange cherry tomatoes, black beans, corn kernels, shredded cheddar, black olives, and diced red onion in distinct sections on top of the lettuce.
Add sautéed taco-seasoned ground beef in a section.
Place avocado slices and tortilla chips in separate sections.
Top with dollops of sour cream and salsa, either in the center or arranged attractively.
Serve immediately to enjoy the crunchy, tender, and colorful textures.
