This is one of the best pasta dishes I have tried in awhile. It has a delicious homemade marinara sauce and a cheese stuffing that is so good. My kids gobbled it up. I pureed the marinara sauce in the blender because my husband doens't like big chunks of tomatoes in anything and I think it enhanced the sauce by really melding the flavors together. This can also be made with whatever herbs and cheeses you have on hand, plus it makes two casserole dishes so you can freeze one for another night. My kind of recipe, this one is definitely a keeper.

Coat 2 (13 x 9-inch) baking dishes with cooking spray; set aside.
