Does anyone know of any good high protein/fat foods that kids can eat while they're playing? I should add that we are vegetarians (lacto/ovo). DD eats a LOT, but mostly when she's running around the house, so her snacks consist mostly of things like organic animal crackers, apples slices, and carrot sticks. She's in the 3rd percentile for weight, so I'm really trying to pay attention to everything she eats.
Thanks for your help!
