How Apple Pie Became 'American'

In the rest of Europe, there is no association of the US with the Apple Pie, and until very recently, there was nothing cooler than US-stuff or US-style stuff. I guess the bakeries would have been filled with American style apple pie.
Coca Cola and McDonald is synonymous with US food where I come from.
Edit: Pizza is a better example than tomatoes. It is American yet has become synonymous of Italian food.
"""Stephen Jenkins noted that the feedback phenomenon could continue; in the case of pizza, he wrote that the return of pizza to Italy again influenced American cuisine: "...pizza-loving American tourists, going to Italy in the millions, sought out authentic Italian pizza. Italians, responding to this demand, developed pizzerias to meet American expectations. Delighted with their discovery of "authentic" Italian pizza, Americans subsequently developed chains of "authentic" Italian brick-oven pizzerias. Hence, Americans met their own reflection in the other and were delighted."""
-- Stephen Jenkins (2002), "Black ships, Blavatsky, and the Pizza effect: critical self-consciousness as a thematic foundation for courses in Buddhist studies", in Victor Sōgen Hori; Richard P. Hayes; James Mark Shields, Teaching Buddhism in the West: from the wheel to the Web
It's the sort of feedback mechanism that really brings out the cool effects various cultures have on each other. Not only can one culture co-opt an idea, but the original may take it back and own it, only to have it co-opted again. It's a sort of cultural evolution. (And let's be honest, brick-oven pizzas really are superior to everything else, so I'm not going to complain.)
But there's no point acting offended or put off about it. Americans certainly aren't the first or last to do it. But it's certainly done with gusto.
Americans, on the other hand, look nothing like each other. So it's striking for an American to go to another country and see people who all look very similar to each other, because we don't see that at home.
