I actually just use kibble.  I've found that if I am trying to train for a new trick and the treat is TOO yummy, they won't focus.  I save the good stuff for rewarding something that's a really big deal.  Otherwise regular old training, gets regular old kibble.   
Other than that, I give cucumbers, tomatoes, and various veggies and fruits for just because treats.
