Snackin'

What is your toddlers favorite snack?  I am on the search for some good snacks for a 1 year old.  In the beginning he was the best eater ever.  He would eat avocado, squash, zuccini, cauliflower, peas, carrots, and hummus to name a few.  Then in the last few weeks he has gone from trying everything and liking it to snubbing almost everything.  Applesauce is our go-to food right now, but we really want him to branch out.  So at each meal time we try a few different items, if he "says" no (with his crazy head turning) then we move on to apple sauce, which he eats until we stop giving it to him.  I am convinced he would eat an entire jar in one sitting (we don't try that though).  So we want to try some new things, any suggestions?
