Heat the oil in a pan, when hot add the mashed potato and cabbage and flatten down like a pancake, or add them as two dollops.
Fry for a few mins on each side. Depending on the size of your pan add 2 eggs and fry (or add to a separate pan) once eggs are cooked to you liking, dish up together and serve with a dollop of ketchup along with a cuppa tea!
