Cheeseburgers and pizza? Two of our favorite things, combined into one.
Preheat oven to 400°F. Heat large nonstick skillet over medium heat until hot. Add Ground Beef; cook 8 to 10 minutes, breaking beef into small crumbles, stirring occasionally. Add pasta sauce, onion, bell pepper, Italian seasoning and salt; continue cooking 5 minutes or until vegetables are crisp-tender, stirring occasionally.
Top each muffin half evenly with beef mixture and cheeses. Bake at 400°F 5 to 7 minutes or until cheese is melted.
