If your sandwich roll isn't already cut in half, go ahead and slice it down the middle.
Layer the Asiago cheese onto the bread and broil until melted (took 2 minutes), I spread just a really thin layer of mayo on the bread before layering the cheese on and broiling. You could use mustard, salad dressing or another sauce that you enjoy. Or just leave it off.
Layer the meats on top of the melted cheese on the bottom sandwich roll.
Top with any veggies you want. I added some baby spinach because I had it to use up and I never hesitate to throw some in when I can. It's good for you and delicious.
Layer on the black olives and banana peppers and any other delicious things you might want.
