Dice onion, pickles & bacon. Lay out the meat salt & pepper both sides, put a thin layer of mustard, onions, pickles & bacon. Roll the meat over trying to pull the meat on the sides into the roll. Secure with toothpicks & if needed secure the ends.

Heat a little oil in a large pot. Brown all sides of the Rouladen. When the Rouladen is browned. Take them out & put them to the side. While you brown some onions & optional garlic in the same pot. (If you brown the onions with the Rouladen, the Rouladen won't brown the way you want.) Put Rouladen back in the pot with the browed onions. Then add beef broth with some water if needed.  Do not cover the Rouladen with the broth.  You can also use water with 1 beef bullion cube & bay leaf.

Cook 1 1/2 hours in a covered pot. Checking and stirring occasionally.  You might need extra water or broth.
