What should I make my very picky friends for dinner?

This Friday, three of my friends are coming over to my house for dinner/movie/hangouts. They are fairly new friends - I only started hanging out with them this year at school. I don't really know what kind of food they like but I do know that two of them are extremely picky. I guess they kind of eat like kids (i.e. potato chips, fried food, etc). They will be coming late in the evening when my parents are out. There won't be any (alcohol) drinking going on. I want to have more than just snacks but I also don't want to spend a lot of money or time on preparation. I'd like to have a variety of food that is tasty, simple, and that will appeal to their "childlike" tastes. I also don't want it to be exclusively finger food - it would be great if it was sort of like a full meal. Ordering pizza could get expensive and I would definitely be footing the bill...so that may not be the greatest option. Also, one of them HATES pasta. I'm out of ideas! Any suggestions?
