Carne Asada with Black Beans

Ingredients

1. 2 tablespoons vegetable oil
2. 4 garlic cloves, minced
3. 1/3 cup ancho chile powder
4. 2 tablespoons cider vinegar
5. 1 1/2 teaspoons dried oregano
6. Water
7. Salt
8. Six 12-ounce boneless rib eye steaks, about 1 inch thick
9. 1 dried chorizo (3 ounces), thinly sliced
10. 1 large white onion, finely chopped
11. Two 15-ounce cans black beans
12. Avocado slices and lime wedges, for serving

1. In a small saucepan, heat 1 tablespoon of the vegetable oil. Add the garlic and cook over moderate heat until fragrant, about 1 minute. Add the chile powder, vinegar, 1 teaspoon of the oregano and 3/4 cup of water and cook over very low heat, whisking occasionally, until the marinade is slightly thickened, about 3 minutes. Season with salt. Transfer the marinade to a large baking dish and let cool completely. Add the steaks and turn to coat. Cover and refrigerate overnight.
2. Light a grill. In a large saucepan, heat the remaining 1 tablespoon of oil. Add the chorizo and cook over moderate heat until crisp, about 4 minutes. Using a slotted spoon, transfer the chorizo to a bowl; reserve it for another use. Add the onion to the saucepan along with the remaining 1/2 teaspoon of oregano and cook until softened, about 6 minutes. Add the beans with their liquid and simmer until slightly thickened, about 10 minutes. Season lightly with salt.
3. Grill the rib eye steaks over moderately high heat, turning once, about 12 minutes for medium-rare meat. Serve the steaks with the black beans, avocado slices and lime wedges.
