How to Make It
Preheat the oven to 425°. Spread the pine nuts in a pie plate and toast in the oven until golden, about 2 minutes. Let cool.
In a small bowl, soak the raisins in the hot water until plump, 10 minutes. Drain.
In a large bowl, soak the bread in the milk until soft, 10 minutes. Using a fork, mash the bread thoroughly, then beat in the egg until fluffy. Add the ground meats to the bowl along with the raisins, salt, pepper, 2 tablespoons of the pine nuts, the 2 tablespoons of oil and 1/2 cup of the cheese. Blend until just incorporated.
Oil a large rimmed baking sheet. Transfer the meat mixture to the prepared baking sheet and form it into a 4-by-8-inch loaf. Drizzle the meat loaf with olive oil. Sprinkle with the remaining 2 tablespoons each of the pine nuts and the provolone cheese, pressing to help them adhere.
Bake the meat loaf in the upper third of the oven for about 25 minutes, until browned on top and an instant-read thermometer inserted in the thickest part registers 165°. Remove from the oven and let stand for about 10 minutes. Cut into thick slices and serve.
