If youve been on the hunt for a quick, full-flavored pasta sauce, look no further. This riff on classic meat sauce swaps in italian sausage for ground beef and jalapeos for green peppers, and gets finished with baby spinach to keep the dish tasting fresh. Thanks to its bold, warming flavors, its the perfect fall supper, and any leftovers can be reheated the next day. Just be sure to save some of the water used to cook the pastathe starchy liquid can be used to loosen the sauce as it re-heats. Serve with a side salad, and a crusty baguette.
