First, put a pot of lightly salted water on and cook the pasta on the lower side of the package recommendations. It’ll hold up better in the salad if it’s cooked the 9 minutes if the package says 9-11.
Then, boil the corn for about 6 minutes. Then, char on the BBQ until about 1/4 of the corn is blackened. If you’re using a can, you can torch it or toss it under the broiler for about 3-7 minutes until it has some colour.
For the dressing, chop and deseed the jalapeños, and dice the green onions, garlic and cilantro. Mix in a bowl with the lime juice and spices. Double the dressing (mayo, lime juice and spices) if you're looking for a creamier salad.
In a large bowl, add the pasta and feta cheese and mix well. Done!
