I only have a 30 minute lunch off a busy highway, so I'm limited in what I can eat during my break. Lately, I've been going to the neighboring Wal-Mart's deli. It's cheap, and the food is delicious.
Today I got Fried Chicken (Leg & Thigh), Okra, and Potato Wedges. Also, 4 BIG boneless buffalo "wings", and a large orange juice. Total? $4.67
Sometimes I'll bring lunch, but I really like to sneak out of the office when I can.
