  1. The texture pleasantly surprised me. Very much like the old fashioned noodle version. I did add mushrooms and olives to mine, just because is what I am used to having in tuna noodle casserole. Thank you from someone who has gluten induced psoriasis and seborrhea. I finally have one of the comfort foods back!
