Ross' Stuffed Burgers

Form ground beef into 8 patties (1/4 lb. ea.) about 5" in diameter. Place patties on waxed paper for ease of handling. Working with 4 patties, place one rounded tablespoon each of pickles, olives, mushrooms, onions, and cheese onto the center of each patty, leaving about 1/2" of meat exposed all the way around. Add several dashes of Worchester sauce, several dashes of Tabasco sauce and several turns of the peppermill onto the center of the "stuffing" pile. Place another beef patty on top of each of the 4 prepared patties. Carefully pinch and twist edges of beef together to completely seal edges. Once formed together, pick up burger with waxed paper underneath and make sure that edges are well sealed.
Place stuffed burgers on preheated, medium temperature grill. Brown first side for about 2 minutes. Turn burgers carefully and brush barbeque sauce on the browned sides. Cook another 2 minutes, turn burgers over and again brush with barbeque sauce. Continue to cook over medium heat with lid closed (occasionally turning and reapplying BBQ sauce) for about 10-12 minutes more or until desired doneness. If grill is uncovered, you may need to increase the grilling time.
