my LO has dairy/soy/salicylates intolerance so limited snacking options here too. use a lot of the following:
yoghurt
fruit
pikelets (i usually add fruit of some kind, mashed banana is great)
banana bread
mini muffins (banana, pear and chive are favourites)
scrambled eggs or omelettes (good for sneaking cheese in)
mini quiches (also good for adding cheese)
rice cakes/cruskits/crackers
oat cookies
pasta shapes
rice or wheat puffs
ham pieces
mini toasts
veggie fritters
tinned beans (kidney beans, cannelini beans) or lentils
dried cereal
like i said we are rather limited...
loving the idea of cheese on cracker in microwave, will have to try that when he is back on cheese again
