We do cut up deli meats, crackers, cut up bits of cheese, little pots of baked beans (not heated, DS prefers them right out of the tin), mini bagels, leftovers from dinner, tinned veggies mixed together (peas, carrots and corn are faves)...all things that you don't need to cook or prepare, just put them in some little tupperware pots with lids and you're good to go!
