Plz give me on the road cooking recommendations

 I do gigging work as a drummer for this band, and we're going on tour in a couple days. I've been on 2 tours with them now, and on the previous ones I've been eating HORRIBLY. My stomach feels like it's about to explode into a million bits and pieces by the end of the tours. We're gonna be gone for two weeks and I would like to not feel horrible because I'm eating Taco Bell and bullshit 3 times a day. 

 For anyone who cooks on the go or just likes cooking what are some easy budget meals one could make on the road? (I'm also trying to eat less meat so anyone who is vegetarian or vegan plz give me your awesome/easy recipes, I will be eternally grateful !! :p)
