Leave the bacon in a well-heated pan until it begins to turn brown. Now add the onion cubes and let them brown while stirring.
Add the flour and mix well. First add just a sip of water and mix well. Reduce the heat a little. Then gradually fill up to a glass of water until some sauce has formed.
Now add the mushrooms and let simmer until soft. When they are a little soft, add the Maultaschen strips and pour on the cream. Now stir well, especially scrape off the brown from the bottom of the pan, that makes a nice taste and a great color. Finally season well with pepper, salt, chives and parsley and serve.
