1. Crush coriander roots, garlic, fresh red chillies, salt and crushed peppercorns in a mortar with a pestle. Break eggs in a bowl and whisk lightly.
2. Heat two tablespoons oil in a pan. Add the crushed mixture and sauté. Add onion and the three coloured capsicums, mushrooms and salt and cook for two to three minutes. Set aside and keep warm.
3. Heat a little oil in another pan. Make a cone with gateway paper with a very small hole in the pointed end. Pour the eggs into this cone and move it above the surface of the pan so that a trail of egg flows into it and sets in threads.
4. Keep moving the cone to make three to four crisscross layers of threads. Using a spatula, transfer the nest onto an absorbent paper and make more nests similarly. Place the nests on a flat surface, place some of the mixed vegetables over each and fold the sides over.
5. Serve immediately.
