If you are tired of trying to convince everyone to eat their vegetables, let us help. This casserole dish combines carrots, corn, green beans, onions with a healthy portion of cheese and tops it all off with buttered cracker crumbs for a delicious, crisp finish. Sounds pretty good, right? Okay . . . we admit our roasted vegetables might be a little bit healthier, but you won't have to worry about your veggie skeptics nearly as much when serving this cheesy casserole!
