For me and my fiancee, we usually get a can of Pringles each (so we don't fight over them, as usual), slim jims, a couple bags of candy that we both like (and usually some kind of gummy thing like Gushers or worms xD), and a ton of water and soda. Sometimes I get some of those Starbucks doubleshot drinks because I can't stand the taste of most energy drinks. He's usually good without energy drinks, as I'm the one that fades faster.

For meals, we'll usually get something easily microwaveable or something you can just stick in the oven and not have to watch. Usually ramen for me, and those Totino's party pizzas for him! Actually, if you're looking for something easy and good to eat for breakfast, Banquet makes breakfast pot pies now. The sausage and gravy one is beast. Just stick it in the oven for 30 minutes xD
