As for crunchy- these are a little too fragile to use for dip, but kale crisps made in the dehydrator are SO good, easy, and satisfy that need for snacky crunchiness. The recipe I fund called for kale, a touch of raw honey, coconut oil, lemon juice, and sea salt.
I second the vote for the dehydrator. Since I started following PB, the dehydrator, the CrockPot, and the Cuisinart have been on heavy rotation at my house. I have used those three things more in the last few months than I had over the last 7 years combined! The bread machine and the toaster, however....their days are numbered.
