1. Bring a large pot of salted water to a boil and cook the rotini until just tender. Drain, rinse briefly under cool water, and let it drain well.

2. In a skillet over medium heat, cook the ground beef until browned and fully cooked. Season lightly with a little salt and pepper, then drain any excess grease and let it cool.

3. Cook the bacon until crisp, then transfer it to a paper towel lined plate. Crumble once cooled.

4. In a medium bowl, whisk together the mayonnaise, sour cream, barbecue sauce, Dijon mustard, lime juice, chili powder, garlic powder, salt, and black pepper until smooth.

5. In a large mixing bowl, combine the cooked pasta, ground beef, bacon, cheddar cheese, cherry tomatoes, corn, black beans, red bell pepper, red onion, and green onions.

6. Pour the dressing over the salad and toss until everything is evenly coated.

7. Cover and refrigerate for at least 30 minutes before serving. Stir again before serving for the best texture and flavor.
