Crispy Cajun onion rings
For a simple side, try oven baking breaded onion rings rather than frying to dramatically cut the fat content
Heat the oil in a deep frying pan, and tip in the mince, breaking it up with a wooden spoon as you go, until browned all over. Stir in the onion and pepper and cook for 8-10 mins until softened. Tip in the tomatoes and Nando's PERi-BBQ sauce, and season. Simmer for 20-25 mins until the sauce has thickened.
Put the cheese slices on top of the mince and cover with a lid for 2 mins to let it melt into the sauce. Pile into the buns with the crispy onions, and lettuce on the side for scooping up the extra sauce.
