Open-Faced Pizza Burgers

Directions

• In a large skillet, cook beef and onion over medium heat until the meat is no longer pink, 3-5 minutes, breaking into crumbles. Drain. Stir in the pizza sauce, mushrooms, sugar and oregano; mix well. Spoon onto buns; sprinkle with mozzarella cheese.
• Place on ungreased baking sheets. Broil 4 in. from the heat until cheese is melted, 2 minutes.
• To freeze for quick lunches later, place the split and toasted buns on a baking sheet. Spoon the meat mixture onto buns; freeze for 1 hour. Transfer to freezer-safe airtight containers.
• To use frozen burgers: Thaw completely in the refrigerator. Sprinkle with cheese. Broil 4 in. from the heat until heated through and cheese is melted, 2 minutes.
