Mix all of the burger ingredients together in a bowl. Season and shape into 8 burgers.
Preheat the grill. Arrange the burgers on a baking sheet and put a little butter or margarine and Marmite (optional) on each one. Cook under a hot grill for about 5 minutes each side under until cooked through in the middle.
Alternatively to fry – heat the oil in a frying pan. Fry the burgers for about 5 to 6 minutes, turning half way through until lightly golden and cooked through in the middle.
Serve on their own or with mini buns or bagels and a little mayonnaise or ketchup and salad.
