I'm particularly fond of this nachos recipe from Moosewood - I even kid myself it's healthy as it has tomatoes and capsicums in it!

Cook onions, add toms and pepper, and herbs, then add beer/lager. Simmer till lager is right down (about 15-20 mins at the most) then take off heat and add cheese, stirring until it's melted. Add to large plate of Doritos plain tortilla chips and eat before it gets cool.
