Well I hope you enjoyed your dinner at least. They just need to learn to make their own food (even if it's PB&J) if they're going to reject perfectly healthy and delicious options. I used to be a super picky eater, and then a friend (who now happens to be my husband) convinced me to start trying foods and forget that I don't like them. Pretend they're some mystery food I have no preconceived notions about. And guess what, I actually liked most of the foods I hated before. (I still do not care for nuts or mushrooms, but am perfectly okay with picking them off of food).
