Place all the ingredients in a large mixing bowl and combine well. With a potato masher (or your hands) mash everything together well until the mixture is sticky.
Form into patties and black on a lightly oiled sheet pan (or one lined in parchment paper) and bake for 15 minutes at 350 F.
Allow to cool and store in a covered container.
When preparing to serve, sear the patties in a skillet on both sides and top with a piece of vegan cheese. Place under the broiler for a few minutes to melt the cheese.
When the cheese is melted, place on a bun of your choice and top with lettuce, sliced tomato, sliced onion, pickles, mustard and ketchup.
