Chiles Rellenos (Serves 4)
For the peppers:
4 poblano peppers
3 tablespoons corn or olive oil
1/2 onion, chopped
2 garlic cloves, finely chopped
Salt and freshly ground black pepper
10 ounces baby spinach
1 (14-ounce) can black beans, rinsed and drained
4 ounces goat cheese
For the sauce:
3 dried Mexican chiles (such as Ancho or Guajillo)
2 tablespoons corn or olive oil
1/2 onion, chopped
4 garlic cloves, finely chopped
2 cups fresh or canned tomatoes, chopped
1 teaspoon ground cumin
Salt and freshly ground black pepper
Directions
Make the stuffed peppers: Place the peppers on a grill over direct heat and blacken all over, turning occasionally, about 6 minutes. Place peppers in a bowl and cover bowl with a plate. Let peppers steam until cool, then discard skins, stems, and seeds.
Heat oil in a large, heavy skillet over medium-high heat until hot, then stir in onion and garlic along with 1/2 teaspoon each salt and pepper, cooking until onion is browned, about 6 minutes. Stir in spinach, a handful at a time and cook, turning with tongs until wilted. Add more spinach, turning with tongs, until all of the spinach is wilted and water from spinach has evaporated. Stir in beans and season with salt and pepper to taste.
Let filling cool, then crumble cheese into filling. Divide filling between peppers, closing peppers around filling. Place peppers in a baking dish.
Make the sauce: Discard the stems and seeds from chiles, then toast in a dry, heavy skillet over medium heat. Soak chiles in hot water until pliable, about 10 minutes.
Heat oil in a large, heavy skillet over medium-high heat until hot, then saute onion and garlic with 1/2 teaspoon each salt and pepper until golden, about 6 minutes. Puree tomatoes, chiles, and cumin in a blender. Add tomatoes mixture to skillet and cook until thickened, about 10 minutes. Season sauce with salt and pepper to taste. Pour sauce over chiles in baking dish. Just before serving, heat chiles in a 350° F oven until hot.
