Lunch ideas for picky 3 year old....

Hi! My 3 year old is in a half day program through the local school system. He will be there through their scheduled lunch time, he's young and a super picky eater. I would love a healthier version of a Lunchable, he will eat cheese, crackers, fruit, some meats. He's also a pasta eater but that's too messy to send. I want something easy to send and am in the States if that helps. 💙 💙 💙
