Originally called the Ploughman's Sandwich, I have changed this to a vegetarian sandwich by leaving out 5 oz. corned beef. Feel free to add it if you want to! The original recipe also called for Irish cheddar cheese to be soaked in Guinness beer for 2 hours. Hmmm. This is supposed to be one serving! I'm calling it two servings!
