Snacks ideas

Hi all, I have been off for a while because we moved to another house (that was a mess), so I am behind on quite a few postings. I need help, though! I am starting ABA with my son this weekend and I am looking for ideas for gfcf reinforcers. I am going to use potato chips and crispy cooked bacon,but I need more ideas. I didn't wanted to do icecream or cookies, because, my son's breakfast and regular snacks are already limited to few items. How about dried fruits? any suggestions on what kind doesn't give "diahrrea"? raisins are a no-no here, because they make him poop a lot. Thanks for any ideas. I'll go also for anything I have to cook, like special muffins or something like that. I just have to start now getting ready for Friday.
