Baked Spaghetti with Ricotta

Last night was a busy night.  I had a chiropractor appointment at 5:30 and teach (well, aide) religion class at 6:00.  I knew I was going to be late to both, even though we ate dinner at 4:45!  I boiled a 1/2 box of whole wheat spaghetti.  I drained it and saved 1c of the pasta water.  I mixed the pasta water and 1c ricotta cheese in with the noodles.  Then I topped it with a jar of marinara and some shredded mozzarella.  I baked it at 400 for about 15-20 minutes or until the cheese is bubbly and the sauce is heated through.  Serve with a salad and you're done!  I didn't have time to add ground beef, so the ricotta served as my protein in this meal.  I don't think it's my family's favorite spaghetti, but it was pretty good.
