Baked Ziti Anyone?

How many calories would you estimate is in a serving of baked ziti? The sauce in it was marinara, so no meat, and I ate little to none of the motzerella cheese, because there wasn't much in my serving!

 I have made baked ziti a lot.  I would estimate a one cup serving would be about 350-400 calories.  This is 1 cup of ziti noodles (200), 1/2 cup sauce or less (50) and a ounce of italian cheeses (around 100).  This is just how I make mine.  I would imagine all homemade ziti is about the same.  Hope this helps!
