I enjoyed a whirlwind of Italian cooking in the past week or so - making sauce, spaghetti, pizza, and lasagna. I realized I had a lot of leftover ingredients from these meals, and decided to use them all in one final leftover recipe. This is based on a spaghetti pie I learned to make when I just got married. It is meatless, but you could certainly add some, or even use a meat sauce. It's extremely versatile, and lends itself well to whatever you need to use up in the fridge. In my case, I still had whole wheat thin spaghetti, ricotta, mozzarella, and olives and mushrooms from the pizza, so that's what I used.
