For some reason, Super Bowl foods tend to be pretty meat-centric. When I think game day foods, I think chili (with ground turkey or beef), burgers, steaks or Italian hoagies (also known as subs/grinders/heros/po'boy in other parts of the country) stacked high with salami. But there are lots of other things that make good, warming, stick to your ribs game food (important if you plan on playing a half-time game of touch football).
Recently I made a pot of Broccoli and Cheddar Soup, which would make a great Super Bowl offering. It uses a full half pound of cheddar (the sharper the better) so your carnivores will feel satisfied, but also incorporates several large heads of broccoli, making it feel slightly healthy. It can also be made the day before and reheated, which is always a nice feature when you're cooking for a crowd.
