I know the question has been asked many times but I'll do it anyways.

Today my boyfriend had surgery done on his mouth, and will be unable to eat solid foods for about 3 weeks. It got bad today and when I asked about what he was going to do about eating lunches (high school, don't really have many options) and he said he would probably bring soup to school with him or just eat the schools soup (even majority of the time it is chunky and he would not be able to chew it).
Since I have lunch with him every other day, I thought I could at least try to offer some variety by bringing him lunches that he can eat but aren't completely unhealthy for his body either.

Basically, I need foods or even recipes of things that I can make and bring to school (keep in mind it would have to sit for a while before lunch begins, though I have access to a refrigerator).

Thank you so much for the help, it really means a lot to me.
