This thread makes me curious, have you Americans ever ate pic related? Pork knuckles with potato salad. It's my favorite food here and I could never live without it anymore. It's like the roasted chicken but 100 times better with a very crunchy delicious skin. If you drink a beer before and have that slight tipsy vibe, it tastes even better. Reminds me that tomorrow is saturday and I'm probably going there for lunch again, good my wife is driving.
I think German food is to the core very basic and more about the meat itself. Less spices, less work, just show it's main ingredient form the best side. Maybe? not sure. But that would explain why it's not so popular, because it's not as flashy as your nice burito full of flavors and colors.
