Tasty recipe that I will make again. I did make some changes but don't believe that they affected the flavor profile. I halved the recipe and I didn't use the Smoky Marinara recipe because I already had Marinara Magnifica, which I had made with fire-roasted tomatoes. Unfortunately, I had forgotten to buy provolone but used mozzarella instead. Also, replaced the oven-ready pasta with whole-wheat lasagna noodles and just refrigerated overnight so the noodles softened. Since I halved the recipe and couldn't find fat-free ricotta, I just used pureed fat-free cottage cheese in lieu of the ricotta. FYI, using Trader Joe's peeled and chopped butternut squash saved a lot of time.
