To prepare a spicy vegetable curry with coconut milk, you will first need to prepare the vegetables. Cut the onions and garlic and add them to the pan. Add the curry paste and cook it for about 5 minutes. Then add the carrots, ginger, garlic, green chilies and salt and pepper to taste. Bring the mixture to boil, then reduce the heat to low and simmer for 10 to 15 minutes, stirring occasionally. Remove from heat and stir in the turmeric powder, coriander powder and fenugreek seeds. Serve hot with roti or basmati rice.
