1 poblano pepper, seeded and sliced thin

1 cup grape tomatoes, halved

1 cup frozen corn

1/4 cup Greek yogurt

1/2 cup crumbled feta

Oil, salt and pepper

Let cook without disturbing until beginning to char, about 3 minutes. Add 1 tablespoon oil, then stir in tomatoes and let cook until beginning to wrinkle, about 2 minutes.
