Screw trying to figure out what foods are truly 100% American, and just toss a few foods that taste good together and call it a meal thereby illustrating the "melting pot" idea that was previously mentioned.
For example, get a cheese pizza and add General Tso's chicken as the topping and have sides consisting of French fries, fried chicken wings, and riblets. And yes, I have eaten all of those together as a meal before, and it was delicious.
