Ingredients:

• 3 cups (packed) skinless duck breast fillets, cut into 1/2-inch cubes
• 1/2 pound ground pork
• 1/3 cup yellow onion, finely diced
• 1/4 cup red bell pepper, seeded and minced
• 2 garlic cloves, minced
• 1 or 2 chipotle peppers in adobo sauce, minced 
• 1/2 cup plain breadcrumbs
• 1/2 teaspoon freshly ground black pepper
• 1/2 teaspoon kosher salt (or 1/3 teaspoon table salt)
• 6 slices pepper jack cheese
• 6 hamburger buns
• Lettuce, thick-sliced tomato, and sliced red onion

Instructions:

1. Place cubed duck in a food processor and pulse a few times until the meat is roughly pea-sized. Be careful not to overprocess the meat. It should be a little lumpy. 
2. In a large bowl, combine processed duck with ground pork, onion, bell pepper, garlic, chipotle peppers, breadcrumbs, black pepper, and salt. Mix together well with your hands. Form into 6 equal-size balls and press them into patties about 1-inch thick. 
3. Place patties on a well-oiled medium-hot grill or in a skillet. Brown one side, about 3 to 4 minutes. Flip patties over; cook another 2 to 3 minutes. Top each with cheese and cook until cheese is melted and burger reaches desired doneness. Serve in buns with lettuce, tomato, and red onion.
