Cook the rotini pasta according to package directions. Drain and rinse with cold water. Set aside.
In a large skillet over medium heat, cook the chopped bacon until crispy. Remove and drain on paper towels.
In the same skillet, cook the ground beef. Season with salt, pepper, garlic powder, and onion powder. Drain any excess grease and let it cool.
In a large bowl, combine the pasta, cooked bacon, ground beef, tomatoes, corn, cheddar, red onion, and parsley.
In a separate bowl, whisk together mayonnaise, barbecue sauce, and Dijon mustard until smooth.
Pour the dressing over the pasta mixture and toss to coat evenly.
Chill in the refrigerator for at least 1 hour before serving for best flavor.
