Cook the pasta to al dente according to package instructions. Rinse with cool water, drain, and place in a large serving bowl. Add the corn, black beans, cherry tomatoes, avocados, green onions, jalapeno, and cilantro.
To make the dressing, in a small bowl or large measuring cup, stir together the Greek yogurt, olive oil, lime zest and juice, hot sauce, salt, chili powder, and smoked paprika. Taste and add additional salt or spices as desired.
Pour over the pasta mixture. Toss to coat, then sprinkle the feta over the top. If time allows, chill for 2 hours prior to serving or enjoy immediately.
Notes
Make the dressing and cook the pasta up to 1 day in advance. Toss together up to 4 hours before serving.
