Boil the potatoes and cut them into slices. Meanwhile, cut the bell pepper into cubes and sauté in a little fat in a coated, closed pan. After 10 minutes add the potatoes, mix and pour in the vegetable stock.
Dice the onion and add it to the pan. Season to taste with pepper, salt, nutmeg, curry and herbs of Provence. Let it simmer without a lid until the liquid has almost evaporated.
Mix the egg and cream and spread over the pan. Sprinkle the grated Gouda on top. Simmer for 10-15 minutes over medium heat until the cream and egg are set and the cheese has spread out well.
