We have a salad bar here which has hard boiled eggs, tuna, and grilled chicken at the end of it. So I just make a big salad, craploads of eggs and chicken, and then salad dressing or oil/vinegar.
I’ve found the easiest approach to cafeteria food is to follow the “balanced, non-mixing” approach to food, meaning P+C or P+F meals. So if I put together a salad with chicken and I also made myself a sandwich, I’d use low-fat dressing on my salad. But if I didn’t have carbs, I’d utilize a fattier dressing to compensate.
This method allows for a lot more variety besides salad. There’s hardly any cooked vegetables here, which sucks, so I basically have salad to eat or…salad.
Another method I’ve used is using a modified V-Diet. Basically, all meals are V-Diet shakes except when you go to the dining hall, go out, or are drinking. It keeps calories low, protein high, keeps you full (for the most part), and is convenient for the college student.
