An old friend of mine posted on Facebook that his daughter had hit it out the ballpark with Irish Nachos. The basic premise was potatoes rather than tortilla chips. She topped with sauteed onions, mushrooms, etc. I baked my potato slices, altho they could be fried, and my other toppings were not greasy, altho, ultimately we ARE talking messy nachos when you get down to eating. I fried the bacon and drained it before topping. Do make your sauce ahead of time as it needs to thicken. These are good and no trouble to put together.
