Gluten Free & Vegan Quinola Burger

Prior to making the burgers, roast the unpeeled sweet potato and let it cool ( you could make it ahead and store it in a fridge). In a frying pan, place the margarine, onion and mushrooms and fry for a few minutes. In a large mixing bowl place the peeled sweet potato and mash it with a fork. Add the fried mushrooms and onion and mix in cumin and cayenne pepper. Add a 1/2tbsp of potato or corn starch, cooked Quinoa and chickpea flour, add salt and pepper to taste. With your hand form the mix into about 8 equal size burger patties. When ready, fry the patties for a couple of minutes on each side. Serve with garnishing and sauce.
