First, slather about two tablespoons of butternut squash puree onto each lasagna sheet and spread evenly across. Evenly distribute the vegetable medley throughout all the sheets. Next, place small dollops of ricotta across the sheets. Sprinkle with bits of sausage and top with half of the shredded mozzarella. Roll tightly.
*Depending on the size of your pan, you can fit about 10 rolls squished together (my 10-inch pan fit nine).
