Directions

1. Preheat oven to 350 degrees. Place pancetta on a rimmed baking sheet. Bake, flipping the slices halfway through, until crisp, about 15 minutes. Drain on paper towels.
2. Meanwhile, using your hands, combine ground chuck, salt, chili powder, and paprika in a bowl, and season with pepper. Shape into 4 patties (about 4 inches in diameter).
3. Preheat grill to medium. (If you are using a charcoal grill, coals are ready when you can hold your hand 5 inches above grill for just 5 to 6 seconds.) Grill burgers 4 to 5 minutes. Flip burgers, and top with cheese. Grill 3 to 4 minutes more for medium-rare. Remove, and let rest 5 minutes. Top burgers with pancetta, and serve on buns.
