Healthy Toddler Snacks

I was talking with a few mom friends yesterday about the difficulty in finding healthy snacks that toddlers like.  It seems that so much of it is "cracker-based," which, in my opinion, is fine but just gets boring after a while.  Thomas usually gets either Cheerios, graham cracker, rice Chex, or Goldfish. (Note:  in reality, he gets the knock-off brand of each of the aforementioned name brands).  I decided to take matters into my own hands today and did some snack searching.  Throughout this afternoon and evening, I'm hoping to make the following snacks:

homemade sweet potato chips (my own concoction...let me know if you want my very informal recipe)
yogurt-based cookies (no egg!)
raisin granola bars (nut-free)...(from the More with Less cookbook)

I'm still on the look-out for more toddler-friendly snacks...any suggestions?
