General Tso's Chicken
Broccoli Beef
Shrimp fried rice
Garlic Chicken
Moo Goo Gai Pan
Egg Rolls
Won Ton Soup
Crab Puffs (which are sometimes called cheese puffs since they just have cream cheese in them)
I think those are all safe choices for even picky eaters. Some of the stuff listed by other people is funky though!
If you had to choose one to try first, I'd try the General Tso's
