Cut tomatoes in half crosswise; gently squeeze each tomato half to remove seeds. Combine oil, basil, oregano, garlic salt and pepper flakes; mix well. Place tomatoes cut-side up in shallow foil-lined baking dish or pie plate. Spoon oil mixture evenly over surface of tomatoes. In small bowl, combine 6 Cheese Italian Recipe Blend and bread crumbs; sprinkle evenly over tomatoes. Bake at 375°F 15 to 20 minutes or until tomatoes are hot and cheese is melted.
