Heat 1 tbsp. olive oil in a skillet over medium heat.
Add corn and spread in an even layer. Cook 5 minutes, or until corn begins to brown. Stir halfway through and spread the corn evenly in the pan once again.
Remove the corn from the skillet and allow to cool completely.
In a large bowl, mix the corn, grape tomatoes, onion, and cilantro. Set aside.
In a blender, add the lime juice, vinegar, honey, garlic, cilantro, and chile powder. Blend until smooth.
Pour the dressing over the salad and stir to combine.
Season with salt and pepper and serve with crumbled feta cheese on top.
