Mix together the mashed potato and vegetables. Add half the melted Lurpak® Slightly Salted butter. Season with salt and pepper, then form the mixture into 4 large or 8 small patties.
Beat the egg with 1 tbsp cold water in a shallow dish. Put the flour into a second dish and season with salt and pepper. Dip the patties in the beaten egg, then coat in flour.
Heat the remaining butter with the vegetable oil in a frying pan. Fry the patties for 3-4 minutes on each side until golden brown.
At the same time, heat a char-grill pan or the grill. Char-grill or grill the Halloumi until lightly browned, along with the tomatoes. Grill or fry the bacon until crispy.
Top the bubble & squeak with the bacon and Halloumi and serve with the cherry tomatoes, garnished with parsley sprigs.
Cook’s tip: Make the bubble & squeak patties and freeze them (uncooked) to serve another day.
