Quarter the peppers, clean and wash them and place them on a baking tray with the skin side facing upwards. Brown them under the hot grill of the oven until the skin starts to blister. Take out, let it cool down a little and remove the skin.
Peel and slice the garlic. Place the peppers, garlic and rosemary in a bowl, drizzle with olive oil and leave to stand. Grill the lamb chops on the hot grill for about 3 minutes on each side.
Serve with the peppers on plates. Add pepper butter and garnish with basil. A mixed leaf salad tastes good with it.
