Using a potato masher, roughly mash the roasted vegetables.
Add the remaining ingredients, except the oil, and mix thoroughly.
Shape into eight patties and place in the fridge for at least 20 minutes before cooking so that they can firm up.
Heat alittle olive oil in a sauté pan over medium heat and cook each patty for 2–3 minutes on each side.
Serve with your choice of sides, such as pickled beetroot, mashed avocado, Roasted Vegetable Hummus and grilled mushrooms, all topped onto a wholewheat bun, or have it bun-less, if you prefer.
