Cook the Pasta: Boil your macaroni according to the package directions. Drain the pasta and rinse it under cold water so it cools down fast.
Mix the Base: Grab a large mixing bowl. Toss in the cooled macaroni, roasted corn, black beans, and diced bell pepper.
Add the Sauce: Pour your creamy Mexican dressing right over the top of the pasta and veggie mixture.
Season and Boost: Stir everything together gently. Add a pinch of salt and pepper to taste. If you want a bigger protein boost, fold in some diced chicken or ham here.
Chill and Serve: Toss until every single noodle is coated. You can serve it right away, but letting it chill in the fridge for thirty minutes makes it taste even better!
