Buffalo Chicken Cheesesteak Sandwich

I start by buttering a half sub roll with my homemade butter. Then put it in the broiler to toast.
I use sliced chicken breast which I dice up in the hot pan with the spatula while mixing in my homemade Buffalo wing sauce.
I then cover the chicken with a couple of slices of Provalone cheese and then cover the pan so the cheese can melt.
I add my homemade blue cheese sauce to the toasted sub roll before topping it with the chicken and cheese. 
Optional is a leaf of Romaine lettuce.
