2 lb. ground beef
2 medium onions, chopped
1/2 cup chopped green bell pepper
4 tsp. dried Italian seasoning, divided
1/4 cup all-purpose flour
26 oz. jar spaghetti sauce
2 cups shredded mozzarella cheese, divided
13.8 oz. can refrigerated pizza crust or 1 11.3 oz. refrigerated pizza
1 Tbs. olive oil
2 Tbs. grated Parmesan cheese
Cook first 3 ingredients and 3 tsp. Italian seasoning in a large skillet over medium-high heat, stirring until beef crumbles and is no longer pink. Drain well, and return to skillet. Add 1/4 cup flour, stirring until blended. Stir in pasta sauce. Bring mixture to a boil over medium-high heat, stirring constantly. Spoon mixture into a lightly greased 13- x 9-inch baking dish. Sprinkle evenly with 1 1/2 cup mozzarella cheese.
Unroll pizza crust, and place on top of cheese. (Tuck edges into baking dish, if necessary.) Brush with olive oil, and sprinkle evenly with remaining 1/2 cup mozzarella cheese, Parmesan cheese, and remaining 1 tsp. Italian seasoning. Bake at 425 degrees for 15-20 minutes or until golden brown.
