Goody, I get to be the first reviewer! This was so good and such a difference from the usual tuna noodle casserole. As usual I tweaked it - put in 6 oz of fresh spinach, because that's what I had, instead of green beans. I also used flavored bread crumbs. I have always used my mother's recipe that is so popular, but this is definitely going to be my recipe for tuna noodle casserole from now on (sorry Mom) Thanks Nurse Di - Carole in Orlando
