1/3 cup extra-virgin olive oil, plus more for brushing
3 red or yellow bell peppers (about 1 1/4 pounds), thinly sliced
1 small sweet onion, thinly sliced
3 garlic cloves, thinly sliced
Scant 1/2 cup golden raisins
2 tablespoons drained capers
¼ cup chopped kalamata olives
1 tablespoon sugar
1/4 cup white wine vinegar mixed with 3/4 cup of water
Freshly ground pepper
8 small lamb chops (5 to 6 ounces each)
Preheat the oven to 375°. In a large, deep skillet, heat the 1/3 cup of olive oil until shimmering. Add the peppers, onion and garlic and cook, stirring, until softened and lightly browned, about 10 minutes. Stir in the raisins, capers, olives and sugar. Add the vinegar mixture and simmer over low heat until the peppers are very tender and the liquid is slightly reduced, about 5 minutes. Season with salt and pepper and keep warm.
Heat a cast-iron grill pan until very hot. Brush the lamb chops with olive oil and season with salt and pepper. Grill the chops over high heat until they are lightly charred, about 1 minute per side. Transfer the grill pan to the oven and roast the chops for 3 minutes for medium meat. Serve the lamb chops with the caponata.
