I always thought that when people ask about some country's food, they mean some signature cuisine that the country is well known for. Like hamburgers and hot dogs for US, borsch for Russia or noodles for China. That doesn't necessarily implies, that this country invented that cuisine or that there are no other local dishes. Like French pasta is very similar to China noodles, but both are known have their own cultural significance.
Possibly so, but my point was that talking about a "signature cuisine" of US may be just as hard as describing a "signature cuisine" of Europe, as US if quite big country with different cultures. I don't think e.g. French or Spanish recognize mämmi or Karelian pies (from Finland), let alone consider them as European "signature cuisines".
Sometimes it may be hard within one (European) country as well. Like an ex-colleague of mine (who was in fact from Denmark) once asked somewhere in France, possibly in Paris, one hotel butler whether he knows where there is a good fish restaurant, he said:
"Sure! In Marseille. Hue hue hue hue hue!" (that's how French people laugh)
Damn Frenchies with their sarcastic sense of humor! No wonder they almost lost WWII! Almost!
Edit: I see "Jauheliha" means ground meat, so I guess it's a very specific type of pizza, while frozen pizza can contain all kinds of ingredients (meat, fish, vegetarian).
No they are not frozen, you just cut one end open from the plastic and put it into microwave for a couple of minutes, and eat. It is very basic, like minced meat (both pork and beef, like we Finns tend to like our minced meat), ketchup and cheese. Maybe it has some other ingredients too, but not much.
Every Finn have eaten one (or many) of those at one point of their lives, especially when they were students. It is almost impossible to avoid them.
Yeah we have those frozen pizzas too (from Dr Ötker, Grandiosa etc.), but they are like deluxe pizzas compared to those mudflaps. They are like what you eat on Sundays or other special occasions.
