Classic-Style Lasagne

Directions

1. 1
   Cook sausage and mushrooms in a lightly greased large Dutch oven over medium-high heat, stirring occasionally, 10 to 12 minutes or until meat crumbles and is no longer pink. Drain and return to Dutch oven. Stir in pasta sauce.

   Drain spinach well, pressing between paper towels. Stir together spinach, ricotta cheese, egg, and Parmesan cheese in a large bowl until blended.

Repeat layers twice, gently pressing layers to compact. Top with 2 noodles, 1 cup sausage mixture, and 1/2 cup cheese blend. (Dish will be full.) Repeat procedure with remaining ingredients in another lightly greased 8-inch square baking dish. Place both dishes on an aluminum foil-lined baking sheet.
