Nierenspiesschen

Nierenspiesschen is a traditional offal dish originating from Germany. The dish is usually made with a combination of veal or lamb kidneys, bacon, butter, onions, salt, and pepper. The kidneys are cleaned and cut into thick slices that are quickly sautéed in butter over high heat. They're placed on skewers with blanched bacon and chunks of onions. The skewers are brushed with butter, sprinkled with salt and pepper, and then grilled on all sides until everything is fully cooked. Once done, it's recommended to serve the kidneys, onions, and bacon over buttered sliced of toasted bread.
