In a large mixing bowl, combine vegan mayo and vegan yogurt (or sour cream), lime juice, chili powder, diced jalapeños, chopped cilantro, red onion, and minced garlic. Then add in the toasted corn kernels and stir to combine.
I prefer to add the vegan feta crumbles just before serving. (They can start to melt into the dressing if added too early.) After stirring in the cheese, taste and add more salt, pepper, or lime juice to taste.
Before serving, garnish with extra feta crumbles, cilantro, and an extra sprinkle of chili powder. The salad can be served while still slightly warm, or it can be refrigerated and served chilled. Enjoy as a side salad or as a dip for corn tortilla chips!
