Depending on the size of noodles*, arrange a single layer to cover the bottom of a lightly greased 9” x 13” pan; layer evenly with 3/4 cup spinach mixture, 1 cup sausage mixture, and 1/2 cup cheese blend. Repeat the layers a second time, starting with noodles and ending with mozzarella. [This can also be divided into two 8″-inch square pans.]
