As the saying goes, "Have slow cooker, must soup," (or something like that). In any case, if you do find yourself equipped with a good old-fashioned Crock-Pot, you could do much, much worse than to whip up this super-filling lasagna soup. It's kind of like pasta e fagioli but without the unpronounceable name or the useless beans. Who needs beans when you have bell peppers, mushrooms, and spinach anyway. It also includes 100% more cheese than your standard fagioli, which makes it 100% better. Recipe here.
