I have also used spaghetti squash when I make chicken or eggplant parmesan. After baking the squash, I scoop out the "spaghetti" and layer it in the bottom of the pan cover with the browned chicken or browned breaded eggplant, then marinara over all of it and topped with mozzarella and parmesan. Into the oven 400 if chicken and 350 if eggplant.
