Lay Twinkies in pan. Mix pudding as directed on package; pour over Twinkies. Pour strawberries over pudding, layer bananas over this, spread Cool Whip over bananas. (Nuts can be added before Cool Whip if you desire). Refrigerate overnight.
I have not tried this yet, but it sounds good and since Mike works for Hostess Cakes, the more Twinkies you buy the better for us!
