Mash together the cold roast potatoes, parsnips, cooked carrots, cabbage and sprouts with a little chopped gammon or turkey (optional - replace with extra veg if not using).
Mix the Hellmann's Real Mayonnaise and egg together in a bowl/jug. Pour over the veg mix and use to bind it all together.
Preheat the grill to moderate and heat the oil in a non-stick pan. Fill the pan with the veg mixture and level off the top with a spoon.
Fry over a moderate heat for 5 minutes and then place under a moderate grill until golden brown. Turn out onto a serving dish.
Cook's tip: This recipe tastes great with a side salad. You can increase or decrease the amount of each veg you use, to your taste, as long as the total weight of all vegetables is 750g.
