Hi K.--
I send finger food with my two-year old. She likes bite-sized tortellini with cheese or spinach and cheese filling, peanut butter on crackers, apple slics with skin removed, raisins, Goldfish, etc. When I worked as a toddler teacher though, even the pickiest kids liked chicken nuggets and build-your-own cracker sandwiches with pre-sliced sausage and cheese pieces.
I also have been surprised that my kid eats more at school than she does at home--I think it has a lot to do with seeing her peers eating their food. Good luck!
