The school is telling my mom about all the vegetarian choices they offer, half of which I have never seen?

My mom went to the school today to bring me my lunch box I had forgotten and was asking why there were little to none choices for vegetarians. They took her on a tour of the lunch room, showing her choices I had never seen. They suddenly stopped putting ham on the grilled cheese and salads and the salads were suddenly fresher. Every time I have had to buy my lunch I end up eating some warm "chilled" fruit and a wilted salad. On some days there is absolutely nothing for a vegetarian to eat other than a peanut er sandwich and a tiny, warm, wilted, brown salad. What can I do? The principal is convinced there are enough foods for vegetarians, my mom has talked to her without my knowledge. The lunch ladies do a fabulous job with everything else.
