In a large skillet over medium-high heat, brown 1 pound of lean ground beef for about 6-8 minutes, breaking it apart as it cooks. Drain excess grease, leaving about 3 tablespoons for flavor. Add taco seasoning and cook for another 2 minutes while stirring, then set aside to cool slightly.

While the beef is cooling, bring a pot of salted water to a boil and cook 8 ounces of rotini pasta according to package instructions, usually around 8-10 minutes. Drain the pasta and spread it out on a baking sheet to cool completely.

While the pasta is cooling, dice 1 yellow sweet pepper and 1 small white onion, and halve a cup of grape tomatoes. Ensure your veggies are bite-sized.

In a large mixing bowl, combine the cooled pasta, seasoned ground beef, chopped vegetables, 1 cup of shredded cheddar cheese, and 2 cups of chopped iceberg lettuce. Stir gently to combine.

Add ½ cup of French dressing and ½ cup of sour cream to the bowl, blending them into the salad. Toss until everything is evenly coated.

Just before serving, crush 2 cups of nacho cheese Doritos and fold them gently into the salad.
