Steps
1. Preheat the oven to 400°F.
2. Place the potato cubes in the baking dish and sprinkle lightly with olive oil. Bake for about 30 minutes.
3. In a separate skillet, sauté the onions and mushrooms in some olive oil or clarified butter until lightly browned.
4. Add the tomatoes to the skillet and cook for a further 3-4 minutes.
5. When the potatoes are cooked, remove them from the oven and add the mushroom-onion-tomato mixture on top. Carefully crack 2 eggs over the vegetables.
6. Place the dish back in the oven and bake until the eggs are cooked to your preferred consistency, about 7-10 minutes.
7. Serve the dish hot.
