In large bowl, sprinkle beef with garlic-pepper blend; gently mix until well blended. Shape mixture into 6 balls. Using end of thumb, make a deep depression in each ball, but do not push all the way through. Spoon about 1 tablespoon cheese mixture into each depression. Gently shape beef around cheese mixture, sealing it inside. Press balls to form patties, 1/4 inch thick and about 5 inches in diameter.
