Many vegetables, actually. The trick is to get them involved, in my admittedly limited experience. I could come, make individual sized shepherd's pies with her, get her excited about "making her own dinner"... and in the process, sneak many vegetables into the pie. She will be excited to eat it because she made it herself, and in this way we can get carrots, peas, even onion into her with little to no fuss! And potatoes also.
