I'm also a college student living on a limited budget. We have breakfast and lunch provided for us four days a week. On occasion someone will come and cook for us. There are 13 of us. I attend a leadership internship so we are a small group. At first all I could eat was salad, salad, and more salad. They finally bought some gluten free bread so I can have the option of a sandwich for lunch. There has still been times where I have to worry about cross contamination. For dinner, I usually eat rice and vegetables. That gets old after a while. I bought a bag of gluten free pasta and added spaghetti sauce to it. I eat eggs for breakfast every morning. Rice cakes with peanut butter are good also. Corn tortillas are cheap. Wrapping lettuce with some kind of meat or rice inside of them are a good option.
