Wash the tomatoes, grate them dry and cut them into slices. Heat butter in a large pan and fry the slices of bread in it until crispy on both sides. Spread the bread with 1-2 teaspoons of mustard and cover with slices of tomato.
Heat 2 tablespoons of oil in a frying pan. Fry the steaks in it in portions for about 4 minutes and season with salt and pepper. In the meantime, heat 1 tablespoon of oil in another pan and add 4 eggs.
Fry the fried eggs at medium heat for 2-3 minutes. Put 2 steaks on each bread. Place 1 fried egg on top and season with coarse pepper and salt. Herb quark tastes good with it.
