Baked Spaghetti and Mozzarella

I made baked spaghetti last night. I tweaked this recipe a little bit. I added rotisserie chicken and substituted whole peeled tomatoes for petite diced.  The recipe says to put the whole tomatoes in a food processor and do a rough chop. That's the same as diced, right? Who knows. If I made it again, i would still use the diced, but also add a can of tomato sauce. The spaghetti soaked up all the liquid when it baked. I would also just skip the sauce making part and just use a jar of marinara sauce. I would definitely make this again. Moma, I used your Dreamfields pasta like a good girl.
