Prep the veg - Strip the corn kernels from the cobs. Destem, deseed, and dice the peppers. Grate the garlic into the bowl where you'll be making the dressing. Chop the cilantro.
Mix the dressing - Squeeze the lime and mix it into the garlic. Stir in the mayo and chipotle powder until combined. Fold in the feta.
Sauté the corn - Melt the butter in a large skillet over medium high heat. Sauté the corn kernels and peppers in the butter, stirring occasionally, until cooked through. Turn up the heat to high and cook without stirring for 2 minutes to ensure a slight char on the bottom kernels. Remove from the heat and pour into your serving bowl.
Stir together - Pour the dressing over the charred corn and stir to mix.
Garnish and serve - Garnish with chopped cilantro and serve.
