Hi all: I am a p/t AM aide in an elem. school and last year I was asked to sub in the afternoons many times. By the time I got around to lunch, the cafeteria was often closed and a banana+granola bar was never enough for me. I'd get home exhausted and starving at 4 pm. So can you all give me some ideas for a portable dry lunch (besides sandwiches) which is filling too? I don't like taking Greek yogurt, having it sit in my bag for 4 hrs and then bring it back home if I don't sub. I feel the yogurt gets spoiled and I don't always park it in the staff refrigerator. Thank you!!
