Peel and finely chop the onion. Peel, wash and roughly dice the potatoes. Heat oil in a pot. Add onion and fry until transparent. Stir in curry paste. Fry the potatoes briefly. Deglaze with coconut milk. Add tomatoes. Season with 3 tbsp soy sauce and simmer for approx. 30 minutes, stirring occasionally.
Boil the eggs in boiling water for about 7 minutes until soft. In the meantime, wash the coriander, shake dry, pluck the leaves and, except for a few for garnishing, chop finely. Drain eggs, quench and peel.
If necessary, dilute the vegetable curry with approx. 100 ml water at the end. Stir in mango chutney. Season curry with soy sauce. Halve the eggs and arrange on the curry. Sprinkle with coriander and garnish.
