Why has it not taken over the world?
Meat, potatoes, gravy, sauerkraut, sausage, beer, etc...
I live in San Diego. Only one German restaurant in a county of 4.5 million+. My neighbor is from Germany and she made a dish called Rouladin the other night. It's a pickle wrapped in bacon, then wrapped in thin sliced beef, kind of like an eggroll but with meat instead of dough. I've been to Germany and thought the food was prime grade.
Then there was the savory gravy and potatoes. Is this available in other places?
