I tried this recipe twice and the 2nd time was better. I used BOTH the cheese (a 2% milk fat Mexican blend) AND some crushed Lays Kettle chips over the top of the cheese. My whole family loved it and it lasted two nights (4 servings each night). I also used less mushrooms (8 ozs) and no red pepper flakes. This recipe beat my grandmother's back in the days when I could eat gluten!
