Stupendous Sensational Spanish Burgers

• 1 1/2 pounds ground chuck
• 1/2 pound chorizo, finely chopped
• 1/3 cup Spanish onion, minced
• 2 cloves garlic, minced
• 1/3 cup Spanish sherry
• 1 1/2 teaspoons kosher salt
• 1/2 teaspoons freshly ground black pepper
• 6 (3" by 4") pieces crusty olive bread, halved lengthwise
• 6 slices of Serrano ham
• 6 ounces shredded Manchego cheese

Prepare a medium-hot fire in a charcoal grill with a cover, or preheat a gas grill to medium-high. To make the patties, combine beef, chorizo, onion, garlic, sherry, salt, and pepper in a large mixing bowl. Handling meat as little as possible to avoid compacting it, mix well. Divide mixture into 6 equal portions and form portions into patties to fit the olive bread. Place patties on the grill, cover, and cook, turning once, just until done, about 4 minutes on each side for medium-rare. During last few minutes of cooking, place olive bread, cut side down, on outer edges of rack to toast lightly. To assemble burgers, on each olive bread bottom place a patty, a slice of Serrano ham, and equal amounts of Manchego cheese. Add olive bread tops and serve.
