Pasta: Cook ½ pound radiatori pasta al dente. Rinse with cold water to cool, drain and place in a large bowl.
Combine: Meanwhile, make 6 ears grilled sweet corn, let cool slightly and cut the kernels off the cobs. In a large bowl, add corn kernels, ¾ cup mayo, ½ cup feta cheese, ⅓ cup red onion, ¼ cup fresh cilantro, ¼ cup cotija cheese, 2 tablespoons garlic, 1 tablespoon lime juice, 2 teaspoons chili powder, ½ teaspoons paprika, ½ teaspoon kosher salt and ¼ teaspoon ground black pepper.
Taste: Stir to combine. Taste and add additional lime juice, salt or other ingredients, per your taste.
Serve: Enjoy immediately and garnish with additional fresh cilantro, red onion, cotija cheese and lime wedges.
Notes
*Corn: you can sub for frozen corn (thaw before use) or even canned corn (drained) if you are in a pinch, but for best results use the grilled corn listed above.
Pasta: feel free to use any small pasta shape you want here.
Storage: store leftovers in an airtight container in the refrigerator for up to 5 days. You may need to add a bit more mayo to help revive it after sitting - the pasta tends to soak up excess moisture so without adding more mayo it may taste dry after sitting.
