In a large bowl, combine the cooked onion mix, mashed chickpeas, oat flour, tahini, and chopped fresh herbs.Stir well to ensure all the ingredients are thoroughly combined.
Shape the mixture into patties by pressing it into a 1/3 cup measuring cup.Carefully place the patties into a heated pan and cook for about 3-5 minutes per side, or until golden brown.
