Cook the pasta by boiling a large pot of salted water. Add rotini pasta and cook for 8-10 minutes or until al dente. Drain and rinse with cold water.

Prepare the vegetables by washing and chopping jalapeño, Roma tomatoes, red bell pepper, and yellow onion. Shred cheese if desired.

Cook the ground beef in a skillet over medium heat for 6-8 minutes, drain excess fat, and add taco seasoning. Stir and cook for another 2-3 minutes.

In a large mixing bowl, combine the cooled pasta, seasoned beef, and prepared vegetables. Add drained corn and rinsed beans, then toss gently.

Drizzle dressing over the salad and toss to coat. Let rest for about 10 minutes.

Just before serving, crush the Doritos and sprinkle on top. Optionally serve over iceberg lettuce.
