2 pounds lean ground beef (90% lean) 
1 cup Italian-style bread crumbs 
3 tablespoons prepared pesto 
1 large egg, lightly beaten 
1 jar (24 ounces) pasta sauce 
1 package (18 ounces) Hawaiian sweet rolls 
12 slices part-skim mozzarella cheese 
1/2 teaspoon dried oregano 
1/4 cup melted butter 
1 tablespoon olive oil 
3 garlic cloves, minced 
1 teaspoon Italian seasoning 
1/2 teaspoon crushed red pepper flakes 
2 tablespoons grated Parmesan cheese 
1 cup shredded part-skim mozzarella cheese or shredded Italian cheese blend 
Minced fresh basil
1. Preheat oven to 350°. Combine ground beef, bread crumbs, pesto and egg; mix lightly. Shape into 12 meatballs; place on a greased rack in a 15x10x1-in. baking pan. Bake until browned and a thermometer reads 160°, about 35 minutes. Toss meatballs with sauce; set aside. 
2. Meanwhile, without separating rolls, cut horizontally in half; arrange bottom halves in a greased 13x9-in. baking dish. Place half the cheese slices over roll bottoms; sprinkle with oregano. Add meatballs and sauce. Top with remaining cheese slices and bun tops. 
3. Combine butter, olive oil, garlic, Italian seasoning and red pepper flakes; brush over buns. Bake, covered, for 20 minutes. Uncover; sprinkle with Parmesan and shredded mozzarella. 
4. Bake, uncovered, until cheese is melted, 10 to 15 minutes longer. Sprinkle with basil before serving.
