- Yield:Serves 4
- Active time: 15 minutes
- Total time:20 minutes
- 3/4 pound boneless pork top round (see note above)
- 3/4 pound boneless beef chuck (see note above)
- 1/4 pound mild cheddar cheese, grated
- 1/2 teaspoon salt
- 1/4 teaspoon freshly-ground black pepper
- 4 burger buns
- 8 Romaine lettuce leaves
- 2 beefsteak tomatos, sliced thick
Trim any sinew or tough connective tissue from pork and beef. Cut the pork and beef into 1-inch cubes and place in a single layer on a rimmed baking sheet or two large plates (see note above). Set the plate in the freezer for 15 minutes. Remove from the freezer and place 1/3 of meat in the bowl of a food processor. Pulse until finely chopped but not mushy, 10 to 15 short pulses. Transfer ground meat to large bowl and repeat with remaining two batches.
Add the shredded cheese to the bowl with the meat. Sprinkle with salt and pepper. Using your hands, gently fold the meat and cheese until well combined. Form the meat into four wide, flat patties about 1 1/2-inches thick. Place the patties on a plate and allow them to sit, covered, for 20 minutes.
Heat a heavy-bottomed non-stick pan over medium flame. Fry the burgers two at a time, if your pan's size will allow it. Heat the burgers until they are well-browned and crisp on one side, then flip them over and repeat. Once the burgers are done, place them on a bun with lettuce and tomato. Repeat with the remaining burgers. Serve immediately.
