Sauté the onion cubes, then add the mushrooms. Add 1 tablespoon soy sauce and toss several times, fry lightly - set aside.
Put the eggs in a bowl and whisk with the milk. Put in the pan, top with the mushroom pieces. As soon as the egg has set, swirl once - fry until golden brown. Arrange on the plate with the rye bread and tomatoes. Cover with chives, season with salt, pepper and a little saffron.
Tip:
If you have yoghurt dressing and like it, drizzle something over it. Gives the scrambled eggs some flavor and variety.
