I like to make this dish for cocktail parties, holidays, or for a day of football and have never received a complaint :)
As for the history of the dish: I threw some ingredients together that I thought would be in the dish and I think it turned out fine. You decide and "chomp" if you like it.
Cheers!
I came across this recipe last year and it was quite a hit at a small cocktail party.
WARNING: if you don't love garlic you will not like this recipe :)
