Mediterranean Stuffed Burgers

Heat grill.

In a medium bowl, mix tomatoes, onion, vinegar, salt and 2 teaspoons oregano. Let stand at room temperature until burgers are ready to eat.

Meanwhile, in a small bowl, mix remaining 1 teaspoon oregano, cheese, lemon peel and oil. Set aside.

In a large bowl, sprinkle beef with garlic-pepper blend and gently mix until well blended. Shape mixture into individual 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-inch in diameter.

Place patties on grill over medium heat. Cover grill and cook 12 to 16 minutes, turning once, until meat is done.

Place burgers on bottom of buns and spoon tomato mixture over burgers. Top with tops of buns.
