1. Bring a large pot of salted water to a boil and cook the rotini until just tender according to the package directions. Drain, rinse under cool water, and let it cool completely.

2. In a skillet over medium heat, cook the ground beef until browned, breaking it into small crumbles. Drain excess grease, then season with salt, black pepper, garlic powder, and onion powder. Let the beef cool.

3. In a medium bowl, whisk together the mayonnaise, ketchup, mustard, sweet pickle relish, white vinegar, and paprika until smooth.

4. In a large mixing bowl, combine the cooled pasta, cooled beef, cheddar cheese, red onion, pickles, and tomatoes.

5. Pour the dressing over the salad and toss until evenly coated.

6. Fold in the chopped lettuce just before serving so it stays crisp.

7. Cover and chill for at least 30 minutes. Sprinkle with sesame seeds before serving if desired.
