For Spain you could have some Iberico Ham, and for Italy, some Parma ham.
Away from ham, here are some (very basic) ideas but hopefully you'll find some inpiration in there somewhere:
France - coq au vin
Spain - Paella or Tapas
Mexico - Fajitas, burritos
Australia - prawns on a bbq
Greece - Kelftiko, spanakopita, dolmades, moussaka
Japan - sushi, ramen
Italy - pasta, pizza, bruschetta
Belgium - fries and mayo
USA - burgers
Portugal - salted cod, sardines
That's all for now, I shall continue to ponder and let you know if I have any more thoughts
