Grilled Skirt Steak with Poblanos
In a medium saucepan, heat 2 tablespoons of olive oil until shimmering. Add the onion and cook over moderate heat, stirring, until softened, about 5 minutes. Add the corn and poblano strips and cook until the corn is tender, about 2 minutes. Stir in the sour cream and season with salt and pepper. Keep the corn warm over very low heat.
Light a grill or preheat a grill pan. Rub the steaks with 2 tablespoons of oil; season with salt and pepper. Grill over high heat, turning once, until lightly charred, about 6 minutes. Let the steaks rest for 5 minutes, then thinly slice across the grain. Serve with the corn and poblanos.
