Preparation:
First, prepare the rolls. From the listed ingredients, knead the dough until smooth and elastic so it pulls away from the bowl. Leave it covered in a warm place for about 1 hour. Then knead the dough again briefly and shape it into rolls. This amount will yield 4 larger or 6 smaller rolls. Leave them again in a warm place to rise until the dough doubles in volume. Sprinkle the rolls with your chosen seeds. In the meantime, place a small bowl of water in the preheating oven so the rolls have a crisp crust and the crumb stays moist. Bake in an oven preheated to 200°C for 20–25 minutes, until golden brown.
Peel the mushrooms, wash them together with the parsley and finely chop everything. Sauté the mushrooms in heated olive oil, add the chopped arugula and cook until the liquid evaporates. Season with salt and pepper. Slice off the top of the roll and hollow out the center. Spread the mushroom mixture over the bottom of the roll, then crack in an egg and cover with the top. Place the roll in an ovenproof dish and put it into an oven preheated to 180°C for 15 minutes. Meanwhile, prepare the salad. Wash the tomato, pat dry and cut into small cubes. Chop the onion and mix it with the tomato. Add the chopped parsley and season with salt, pepper and a pinch of chili to taste. Drizzle with olive oil and mix thoroughly.
