Diet tips?

hello everyone! I came to this group for a little advice on diet stuff! I dont personally have crohns but my bf is having a horrible flare rn and its been bad for a minute. hes on 40 mg of steroids for the next month every day and Im trying to find good some good snacks he can eat, Ive looked online but its soo limited. I just want to know if theres any personal experience here with food thats more snacky thats easier on the stomach. I want to do a movie night with more fun food but want to stick to his dietary needs. Any tips?
