Peel and cut the onions in half.
Process the onions using the grating disc in a food processor or a box grater.
Toss into a colander and press out the excess liquid.
Transfer to a large bowl, add the remaining ingredients and mix until well combined.
Spread about 2 cups of the mix onto a teflex sheet placed on a dehydrator tray.
Repeat with the remainder of the mixture.
Dehydrate at 100 degrees for 24 hours or until it is the texture you prefer.
About 8 hours into the process, once they are dry enough to handle, flip the bread and remove the texflx sheet. Then continue dehydrating.
Once dry, remove, cut up into pieces and store in an air-tight container.
Serve with soup, salad or even make a little thicker and use as a pizza crust or for sandwiches.
