Berta’s Tuna casserole is made with simple ingredients that are assembled and baked. This recipe is courtesy of my ninety year old friend, Berta. She promised me that it had always been a favorite of her family, but I admit to being skeptical about her recommendation. Prior to making this recipe, I had never eaten a tuna casserole. As it turns out, my skepticism was unwarranted. My family loved this. Even Sue Chef deemed it “good” and had a second helping.
