Enchiladas can be a bit of a project, but here, the process has been streamlined, making them a truly possible weeknight endeavor. Begin by sautéing peppers, onions and garlic until charred in spots, then blend half of the vegetables with canned tomatoes and chili powder for the sauce and combine the rest with black beans, shredded cheese and cumin for the filling. If you’re short on time, you could use store-bought enchilada sauce (you'll need three cups), but quality varies, so taste it…
