Authentic German Potato Salad

Ingredients:
2 pounds potatoes
1 large white onions
1 pound bacon
6 tablespoons vinegar
1/3 cup oil
1 cube beef or vegetable boullion
1 bundle green onions
2 tablespoons parsley
3 tablespoons brown mustard - (according to your taste)
Procedure:
Boil peeled or skins-on (according to your preference) potatoes in water and boullion for 15-20 minutes. (This may take longer if you are at high altitude). Don’t let them get to soft- a fork should go in but the potatoes should not fall apart. Fry bacon and crumble bacon into small pieces. Dice the white onion and fry it in the bacon grease. Chop the potatoes into cubes. Mix the bacon, white onion, oil, mustard, and vinegar together in a bowl that will be large enough to hold your potatoes. Chop the green onions. Toss the cooled potatoes in your sauce along with the green onions. Sprinkle with parsley, salt and pepper to taste.
