1 (10-ounce) package frozen chopped spinach
2 pounds ground beef
1 1/2 teaspoons oregano
1/4 teaspoon pepper
1 1/2 tablespoons Worcestershire sauce
1 (10-ounces) package lasagna noodles (we used whole wheat lasagna and it tasted great!)
1 pound Monterey Jack or Mozzarella cheese, grated
2 (10 3/4-ounce) cans cream of mushroom soup
1 1/2 cups milk
1 (8 ounce) can tomato sauce
1/2 cup fresh grated Parmesan cheese
Cook spinach and drain well. Brown beef and drain. Add oregano, pepper and Worcestershire sauce. Cook noodles according to package directions. Arrange half of the noodles in 9"x13" pan, then top with half the meat mixture, half the drained spinach and half the grated cheese. Repeat layers of noodles, meat, spinach and cheese. Combine soup and milk and blend; pour over lasagna and let seep through noodles. Spread tomato sauce on top and sprinkle with Parmesan cheese. Bake for 30 minutes at 350 degrees.
