Panontella

Panontella is a traditional snack or sandwich originating from Rome. It's made with a combination of bread (usually casareccio), pancetta, guanciale, salt, and pepper. The pancetta and guanciale are sliced, folded into small cubes, skewered, seasoned with pepper, and then broiled or grilled over medium heat.

The bread is sliced in half lengthwise and the skewers are blotted with the cut sides of the bread every now and then. The crumb is pressed so that it absorbs the tasty juices. The process is repeated until the guanciale and pancetta are browned. The bread is then cut into slices, topped with the pieces of meat, seasoned with salt, and served piping hot.
