I am late, but better late than never...
These are great for just that! They are dairy, soy, wheat, peanut, sugar (mostly, some cane sugar in the choc chips), corn (and probably more...) FREE!
I have to tell you that THESE are my most favorite ever chips too!!!! I have tried other sweet potato chips too, and these are the best! (And I am not a huge sweet potato fan either.)
And this next one is almost a daily snack for my husband. He spoons a bit of almond butter on his banana and dips it in the mini choc chips and loves it! (You could use peanut butter, but he can't have that and we love almond butter and even make out own too. The choc chips are dairy free too!
I would LOVE to know of any healthy and allergy friendly snacks you want to share!
