Hi,
I'm from Ireland and NO-ONE here eats 'Irish Nachos', however several Irish bars around the world have branded their nacho servings as 'Irish Nachos' - perhaps to sell more Nachos...
The Ingredients are
Waffle-cut french fried potatoes
Shredded jack and cheddar cheese
Chopped green onions
Chopped canned black olives
Sour cream
Salsa
And the Recipe is as follows..
Top fries with onions and olives, cover with cheese and bake until it melts. Serve with sour cream and a nice fresh salsa.
Variations: The ingredients above are a bare minimum. Classic additions include chopped tomato, sliced pepperoncini, and pickled jalapeños. Some folks like guacamole.
If you like meat, consider crumbled bacon, sliced pepperoni, or perhaps chili.
Hope this helps - it sounds yummy
