2 cups biscuit mix
1/2 cup cold water
1 pound ground beef
1/2 cup grated Parmesan cheese
1/4 cup chopped onion
2 tablespoons chopped green bell pepper
1 teaspoon salt
1 teaspoon dried oregano leaves
1/8 teaspoon pepper
12 ounces tomato paste
2 to 3 tomatoes, thinly sliced
8 slices mozzarella cheese, each
about 4 inches square, cut
diagonally into halves
Preheat oven to 450 degrees F.
Grease cookie sheet. Mix biscuit mix and water until soft dough forms; beat vigorously 20 strokes.
Divide dough into halves. Pat each half into a 16 x 4-inch rectangle on a cookie sheet with floured hands. Bake until light brown, 8 to 10 minutes.
Reduce oven temperature to 350 degrees F.
Mix ground beef, Parmesan cheese, onion, green pepper, salt, oregano, pepper and tomato paste; spread over rectangles. Bake until beef is done, 20 to 25 minutes.
Arrange tomatoes down center of each rectangle, overlapping edges; layer mozzarella cheese slices over tomatoes. Bake until cheese is melted, about 5 minutes longer.
