My favorite is Rösti, a hash brown dish that's very common in Zurich, Switzerland. That, and the chocolate truffles were my favorite things when I visited there. There was even a rösti shop at the train station that had about 30 variations of it.
You can add any number of things like bacon, other meats, egg, cream, cheese, etc., but we like them just fried in butter. Probably have them most often accompanying grilled boneless pork chops. [darn, now my mouth is watering]
The secret is to boil the potatoes for about 10 minutes, then remove from the stove, drain, cool in cold water for at least an hour. Grate some onion and the potatoes. When we make these at home, we use a food processor, but on the road a grater would work, just slower. When ready, heat a (cast iron) skillet and add a few pats of butter. Toss in the potatoes and onions, press down and leave alone, then cook on low heat for about 15 minutes until the bottom is evenly browned. Put a large plate over the skillet and invert the skillet so the potatoes end up on the plate. Put the skillet back on the stove and slide the potato "pancake" back onto the skillet, uncooked side down. Cook for another 10-15 minutes. When ready, cut into wedges and serve.

I'm sure this procedure could be adapted to a dutch oven, but I hate to speculate as I've never tried it.
