Directions

1. In medium skillet, saute mushrooms, onion and garlic in butter until tender, about 2 minutes. Combine ground pork, mustard, Worcestershire sauce, salt and pepper; mix well. Shape into 12 patties, about 4 inches in diameter, set aside.
2. Spoon equal portions of mushroom mixture onto center of 6 pork patties. Spread to within 1/2 inch of edge. Top with the remaining 6 patties; seal edges.
3. Place patties on grill about 6 inches over medium-hot coals. Grill 10-15 minutes, turning once, until an instant read thermometer reads 160 degrees F.
4. Serve on buns, if desired. Serves 6.
