Pasta: Cook pasta al dente. Rinse with cold water to cool, drain and place in a large bowl.
Combine: Meanwhile, grill your corn and add corn kernels, mayo, feta, cilantro, lime juice, garlic, chili powder, paprika, salt, pepper, red onion and cotija cheese to the bowl.
Taste: Stir to combine. Taste and add additional lime juice, salt or other ingredients, per your taste.
Serve: Serve 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.
