Stir-fries are fast and easy to cook, but getting the flavors just right can require a long list of aromatics and seasonings. For a streamlined stir-fry that’s still satisfying, lean on high-impact ingredients to drive the flavor of the dish. Christopher Kimball’s Milk Street makes a weeknight-friendly chicken and bell pepper stir-fry using savory-sweet, umami-rich hoisin sauce. Slicing the chicken against the grain, so the muscle fibers are short rather than stringy, keeps it tender. The cooking goes quickly, so be sure the ingredients are prepped and at the ready before you head to the stove.
