The easiest is breakfast the next morning. Chop up the leftovers, meat, potatoes, veggies and throw them into a very large frying pan with some oil. Get them good and hot and dump in a dozen or two eggs and make yourself, and the rest of the guys a fritatta. Some buttered toast and you're done with minimal effort.
For meals, I make most of them before hand and freeze in the foodsaver. Chicken or squirrel or rabbit gumbo, venison or beef/pork chili, pulled pork, bbq brisket, crab and shrimp crusted salmon, smothered sausage and shrimp, stuffed venison roast, etc...
