This was one of the Friday night pasta dishes we had in Miltimber. I made it in the large cast iron pot which went into the oven, making it an easy one pot meal (except for the pasta pot of course). Normally I made a vegetarian version with zucchini or other vegetables instead of the sausage. Always used frozen spinach as fresh was rarely available.
In a large skillet over medium heat, saute turkey sausage. Add onion and garlic and saute until the sausage is cooked through. Use your spoon to break up the sausage while it cooks. Add the can of diced tomatoes, crushed red chili's and pesto and let simmer for 10 minutes. If using frozen spinach add it at this point.
Butter/oil a 4-quart/liter baking dish, add the cooked pasta, then sausage mixture and cheese mixture. Top with a sprinkling of mozzarella and Parmesan.
