* Use 1 4-oz can of mushroom stems and pieces. ~-----------------------------------------------------------------------Mix meat, Worcestershire sauce and seasonings. Shape the mixture into dozen thin patties, each about 10 cm in diameter. Mix the cream cheese and the blue cheese. Top each of 6 patties with the cheese mixture, spreading to within 1 cm of the edge; press the mushrooms into the cheese. Cover each patty with one of the remaining patties, sealing the edges firmly. Broil or grill the patties 10 cm from the heat, turning once, until the desired doneness is reached and cheese is melted, about 10 to 15 minutes.
