Prepare ingredients for the recipe.
Place all the flour in a large bowl. Make a little well in the middle. Place whisked eggs, water and melted butter in to it. Work with a fork to form the dough. You can finish it up by hand.
Divide the dough into eight even pieces. On a floured surface, roll each piece into a long string. Dice each string into small pieces.
At this point you can cook the dumplings or leave them in a freezer for next time.
Bring a pot of salted water to a boil. Throw in dumplings and cook them until they float to the top.
Prepare ingredients for the topping.
Dice mushrooms and saute them in an oiled skillet for about 5 minutes. Add in onions and continue cooking until softened. Season them with salt and pepper.
Stir in bacon pieces and butter, cook for another 5 minutes. Place dumplings into a nonstick skillet, add in sauteed mixture and butter. Cook until they turn golden brown.
