Add these final ingredients to the sauce and cook for about 30 more minutes.
• 10 oz.. thawed frozen spinach (fresh is also optional)
• use about 3/4 of a 16 oz. box bowtie pasta, cooked just under al dente. (If you use the entire box it will sap up too much sauce.)
• 1/2 cup parmesan cheese
• 2- 2/12 cups shredded mozzarella
