Do americans have their own food that is unique to them?

Lately I have been eating out a lot, and when we go out it’s alway to eat some kind of cultural food such as Pho, Italian, Mexican, Thai, etc …

Now I realize that most American food is influenced by other cultures and that most ethnic resturants in America have been ‘americanized’ and usually does not bear a close resembelance to the original origin of the food. However, I’d imagine in the eyes of those not from America those food are not American enough. So if someone from another country want to eat true American food, what would it be?

Here’s my thoughts (excluding fast food resturants which are available over seas anyway):
BBQ Ribs
Any kind of BBQ (pork, beef, chicken, etc)
All kinds of BBQ sandwhiches
Mash Potatoes and Gravy
Coleslaw
Potatoes salad
A true home grilled hamburger and/or hot dog
Buffalow Wings
Philly Cheesesteak sandwich
‘Tex Mex’ (I know this influenced by Mexican food, but really is sort of a unique american food)
Grits
Deep Fried Turkey
S’mores w/Hershey’s chocolate bar, marshmellow, and grahm cracker (please correct me if this is not uniquely american)
Corn on the cob
Sweet Potatoes
Meatloaf (This I learned is uniquely American from some famous international chef on TV who claimed he had never tried it before)

I’m sure there is a lot more that I have not listed and I will continue to add to this list as they come to mind.
