I have been drying some Kale, carrots, celery and leftover bread.
I powdered the veggies in the blender also grinding the bread in to crumbs.
I will be adding the powdered veggies to all sorts of other foods like meat loaf, stews, and anything else I can think of.

The bread crumbs has so many uses as well.
My dh don't like greens so this will be a plus. I will be dehydrating some mustard greens today frozen uncooked.
