In a large skillet, heat olive oil over medium heat. Add ground beef and break it up with a spoon.
Sprinkle in chili powder, cumin, garlic powder, onion powder, smoked paprika, salt, and pepper. Stir and cook for 8–10 minutes until browned and cooked through.
While the beef cooks, make the dressing. Blend Greek yogurt, cilantro, olive oil, lime juice, garlic, salt, and pepper in a blender or food processor until smooth. Thin with water if necessary.
In a large bowl or individual bowls, arrange chopped romaine as the base.
Top with beef, tomatoes, avocado, corn, black beans, cheese, and tortilla chips.
Drizzle with the creamy lime cilantro dressing just before serving.
