I call this 'Boyfriend Meatloaf' because it's a meatloaf that quite a few boyfriends have enjoyed :) It's based on Cooking Light's Pizza-Style Meatloaf, with just a few modifications.
2/3 cup tomato sauce, divided
1 1/2 pounds extra-lean ground round
3/4 cup breadcrumbs
A pinch of dried oregano, basil, and parsley
1/2 cup chopped onion
1 teaspoon Worcestershire sauce
1/2 teaspoon ground red pepper
1/4 teaspoon koser salt
1 large egg
3 oz shredded mozzarella cheese
1 diced red bell pepper
Preheat oven to 350°.
Combine 1/3 cup sauce, meat, and ingredients (sauce through egg) in a bowl.
Shape meat mixture into an rectangle on wax paper. Sprinkle cheeses over meat mixture; sprinkle with red bell pepper, leaving a 1-inch border. Roll meat mixture up jelly-roll fashion starting at short side. Pinch ends to seal.
Place meat loaf on a broiler pan coated with cooking spray. Bake at 350° for 1 hour or until meat loaf registers 160°. Brush 1/3 cup tomato sauce over meat loaf. Bake an additional 5 minutes or until done; let stand 10 minutes before slicing.
