Easy recipe suggestions?

I’m staying at my boyfriends house for a couple days this week, and he doesn’t do a ton of cooking and mostly orders out therefore he doesn’t have very much food in the house lol. He also usually only eats one meal a day because of his work schedule, while I usually eat at least two meals a day. I wanted to make something to bring to eat while I’m there, (preferably something I can do most prep at home) and would love some suggestions! Thanks in advance!
