Some of my son's favorites are:
-deli turkey
-cans of Swanson white meat chicken (although these are really high in sodium so I try not to give it too often)
-pasta pick-ups from Gerber--little raviolis without sauce
-grilled cheese sandwiches torn into little pieces (I cook them in the toaster oven so I don't even need to butter the bread)
-fruit--he loves banana slices, pineapple tidbits, mandarin oranges, kiwi, and Gerber apples, pears, and peaches that come in a jar
-vegetables--he doesn't like these as much but I keep trying. I use frozen veggies because it is easy and doesn't have sodium like canned veggies. Try the peas and carrots, the size is perfect.
-Gerber also now has dehyrdated fruit and veggies, like apples and corn, in bit sizes and he loves those
-Goldfish crackers, graham crackers, melba toast, etc.
Hope that helps with some ideas!
