No veggies available at all? I've never heard of Alfy's cheese pizza, but I should warn you there may be rennet in the cheese. Is there any way for you to bring your own lunch?
I'd call up corporate and ask what cheese they use and if it is animal or vegetable rennet. Also, could you convince the school to offer at least veggie if not this one: ARTICHOKE HEARTS, FETA CHEESE & PESTO Artichoke Hearts, Feta Cheese, Pesto Sauce, Roasted Garlic, Tomatoes and Roasted Red Peppers.
I find it hard to believe that they only serve meat and cheese pizza. Don't they have side dishes/veggies/fruits/breads? You cannot survive on meat alone, they've got to be serving something else.
