Cook the pasta to al dente according to package instructions.
Once tender, drain the noodles and rinse them with cold water.
While the pasta cooks, make the pasta salad dressing. In a small bowl, mix the ranch, sour cream, taco seasoning, and salsa together.
Add the cooked pasta, beans, tomatoes, corn, peppers, onion, cilantro, and cheese into a large bowl.
Pour the dressing over the pasta and veggies. Use a wooden spoon or spatula and gently mix everything together until all of the ingredients are evenly coated.
Garnish with freshly diced avocado, a sprinkle of chopped cilantro and queso fresco, and serve.
