Place all the burger ingredients into a food processor and blitz to a smooth consistency. Spoon the mix into a large bowl and shape into individual patties.
Place each burger patty on a lined baking tray. Bake in the oven for 30 minutes. Flip each burger after 15 minutes.
Take 4 of the patties and place a layer of vegan cheese on top of each and melt under the grill for 2-3 minutes.
Toast the burger buns under the grill before serving.
To serve: Layer your burger bun with patties, lettuce, tomato, gherkin and red onion. Add desired amount of ketchup, vegan mayonnaise and mustard.
