Lasagna Roll Ups

Preheat oven to 350(F) degrees. In a large pot, boil water and cook pasta until slightly underdone (about 8-10 minutes), drain and set aside. While pasta is cooking, in a medium skillet, brown the ground beef. Be sure to break the meat up into small chunks. In a large mixing bowl combine the ricotta cheese, 3/4 of the mozzarella cheese (12 ounces) and 1 cup of Parmesan cheese, mixing until well combined. Next, make sure to squeeze as much excess water as possible out of the thawed spinach, then add to the cheese mixture. To the cheese and spinach mixture, add about 1/2 cup of tomato sauce and mix well. In a large baking dish (or two smaller dishes) pour just enough tomato sauce to cover the bottom of the dish and set aside. To assemble the roll ups: lay out one lasagna noodle and spread with the cheese and spinach mixture, sprinkle with ground beef and roll from one end to the other. Place in baking dish seam side down. Repeat until all noodles have been used. Pour the remaining tomato sauce over the top of each roll up then sprinkle with the remaining mozzarella and Parmesan cheeses. Bake uncovered at 350 degrees for 30 minutes until bubbly and cheese is golden brown.
