Really healthy and delicious muffins. This recipe evolved as I kept trying to make a healthier version of family favorites. I use all organic fruits and veggies. Teff is a grain available in the organic food aisle of the grocery store. I use a variety of fruits and vegitables, any mix will do, I have used blueberries, beets, rhubarb, cherries, etc. My son-in-law tried to use lettuce, but that didn't work. I make my flour mix in huge batches just by mixing all the dry ingredients and storing them in storage bags in the freezer. I usually double the recipe because I have to share these with everyone.
