Thanks! That sounds like a good suggestion. Fruit is my go-to now, but compared to wheat products it isn't as calorie-dense, so to get the same amount of food value takes up a lot of space. In the past I've brought almonds and homemade gluten-free granola bars. I do bring a thermos of tea almost every day, but in general 1 thermos = 1 three-hour class. If I have 3 classes in a day, I will drink all of my tea during the first one. (Temporary solutions: many of the cafeteria ladies will let me use hot water for free if I bring my own teabag from home. I probably can't sustain this if I never actually buy anything at the cafeteria, but if I restrain my purchases to gluten-free things like coffee or soup, I can stay on my diet and have unlimited hot water.)
