6 wide lasagna noodles
1 (15 oz.) container Ricotta cheese
1 (8 oz.) pkg. shredded Mozzarella cheese
1/4 c. grated Parmesan cheese
1 egg
1/4 tsp. salt
1/4 tsp. oregano
1 (32 oz.) jar spaghetti sauce
1 lb. hamburger, browned

Cook lasagna noodles; drain and cool. Meanwhile, brown the hamburger. Mix together in a bowl the Ricotta cheese, Mozzarella cheese, Parmesan cheese, egg, salt and oregano. Cut lasagna noodles in halves crosswise.

On each half, evenly spread approximately 1/4 cup cheese mixture. Roll up each noodle jelly roll fashion. Mix together the hamburger and spaghetti sauce. Into a greased 9x13 inch baking dish, spoon 1 1/2 to 2 cups hamburger mixture. Arrange rolls on sauce and top with remaining sauce mixture. Bake 45 minutes in a 350 degree oven.
