Oh my.  Looks fabulous!  Thanks for posting. 

Here is the link.  I am sure bil said he saw Robert Irvine make this on his Restaurant Impossible show. 

He used no bake noodles.  We did not have zucchini in it either, but that would be good.

EasyServes:
8 servings.Ingredients
1 cup pumpkin puree
1 1/2 tablespoons extra-virgin olive oil
1 medium onion, chopped
4 to 6 cloves garlic, sliced
1 pound spicy Italian sausage, casings removed
1/2 cup red wine
1 28-ounce can tomato sauce
1/4 cup chopped fresh basil
1/4 cup chopped fresh parsley
1/2 teaspoon dried oregano
Kosher salt and freshly ground pepper
1 16-ounce box lasagna noodles
1 large egg
2 1/2 cups ricotta cheese
2 cups shredded mozzarella cheese
1/2 cup shredded romano cheese
1 large zucchini, very thinly sliced
Directions
Preheat the oven to 350 degrees. Place the pumpkin puree in a fine sieve over a bowl; set aside to drain while you make the sauce.


Heat 1 tablespoon olive oil in a medium pot over medium heat. Add the onion and saute until translucent, 6 to 7 minutes. Add the garlic and cook until fragrant, 2 more minutes. Add the sausage and cook until brown, breaking it up with a wooden spoon. Pour in the wine and cook until reduced by half. Stir in the tomato sauce and herbs and bring to a simmer over medium-low heat. Season with salt and pepper, cover and reduce the heat to low. Simmer 15 minutes, stirring occasionally.


Meanwhile, bring a large pot of salted water to a boil. Add the lasagna noodles and cook as the label directs. Drain and toss with the remaining 1/2 tablespoon olive oil.


Mix the strained pumpkin puree with the egg in a bowl and season with salt and pepper. In a separate bowl, mix the ricotta, 1 cup mozzarella and the romano.


Build your lasagna in a 9-by-13-inch baking dish: Start with a layer of sauce, then top with a layer of noodles. Evenly spread half of the pumpkin filling, then half of the zucchini, over the noodles. Top with half of the cheese mixture and cover with some of the sauce. Repeat the layers, finishing with noodles and sauce; sprinkle with the remaining 1 cup mozzarella. Bake, uncovered, 35 to 40 minutes, or until bubbly. Let cool 15 minutes before slicing.
