Whisk the eggs with the milk and soak the bread
slices in this mixture. Stir fry the onions with the nettle tops for
three minutes. Fry the soaked bread slices on one side in hot oil,
turn them around; distribute the nettle mixture over the bread
slices, followed by the cheese. Put a lid on the pan and simmer for
approximately 3 minutes.
Cook the potatoes for 20 minutes and slice them
thinly. Arrange them on a plate, spread a little mustard on each
slice and sprinkle with salt and fresh milled pepper. Cut the
herring in pieces. Put first the herring and then the onion
slices on top.
