I have been a pescatarian for 14 years and just recently started to get a bit sensitive to gluten (I think- I haven't rigorously tested it yet).
I think it will be challenging to be gluten-free and vegetarian on a college meal plan. I can't tell from your post if you do or don't eat eggs, but here are some ideas for lunches:
- taco salads (cabbage topped with beans, salsa, cheese)
- tacos (with corn tortillas)
- veg soups when available (broccoli, cream of spinach, tomato, etc)
- lentil soups when available
- egg drop soup
- Indian food, if they ever serve ethnic meals (dal, channa masala, curried vegetables)
- Mediterranean dishes: hummus, baba ghanoush
- Chinese stir fries (to mix up the usual stir fries it sounds like you're having)
- Veg sushi (if your college ever serves that)
- tofu-based dishes
- lots of beans and lentils
I would say Thai food (curries, pad thai with rice noodles), but all Thai food has fish sauce in it so it may not work.
A lot of this depends on what your college serves. To be honest, if you find that you are relegated to fries and salads for the rest of the year on your diet, it may be worth considering adding in fish or poultry to your diet. I say this as a vegetarian, so I know how difficult it is to eat meat when you don't want to. I haven't eaten it in 15+ years!
BUT I went to a university which offered vegetarian options every single day, so I was able to get in all my protein and vitamins. After my freshman year I got out of the meal plan so I could manage my own food.
Your health is most important, so if you feel that your university's meal plan (I assume it's required for freshman?) doesn't allow you to adhere to your dietary restrictions while being healthy, you may either want to consider 1) shifting your diet slightly or 2) trying to cook more food by yourself in your dorm. The latter is really difficult, i know, which is why the former might be more of an option.
Again, it all depends on what your dining hall offers. I just think it's useful to consider your health and adapting your diet (temporarily!) if your future just looks like fries and salads. Good luck!
