For gas stoves, place the whole peppers directly on burners flipping them with tongs until they are black all over. Or if you use an oven, roast for 10-12 minutes at 350 degrees F on a greased baking tray, turning approximately every 4 minutes. When finished, peel off the skin and remove the seeds and stem.
Chop and saute onions for 3-5 minutes. Now add all ingredients to the blender. Serve with brown rice cakes.
