Pancakes are cooked, BTW, so that part of your question is odd, but to answer the mixing of eggs and pancakes on the same plate, I don't mind if the eggs are scrambled (another point you neglected to mention, how the eggs are prepared) rather than sunny side up, but if they are just sunny side up then I would definitely have them on a separate plate. Why do people like you always feel the need to frame these questions mentioning Americans? I doubt America is the only country in the world that serves pancakes and eggs on the same plate.
