Nuke, Frito pie is the most primo 7-11 food there is.  Buy a small bag of Fritos, cut it open on the face so it makes a bowl, go to the scum-dog fixings and add chili and cheese.  Voila!  Frito pie, and if you don't have a fork, open the bag the regular way, squirt the goo in, shake, and eat it like an astronaut (squeeze it into your mouth from the bag).
