Split lengthwise, leaving one side joined.
Mix all the condiments and salt in a small plate and use this to fill the split okra.
Chop the onions and tomato lengthwise.
Warm the oil in a microwave safe glass dish for 2 mins.
Place the masala-filled okra, chopped tomatoes, chopped onions and whole green chillies in the oil and mix well with a wooden spatula.
Sprinkle the leftover masala on the okra.
Microwave on high for 15 minutes. Remove the dish, mix well with the spatula, and if the vegetables appear dry and uncooked, add 1/4 cup of water by sprinkling it on the vegetables and mixing again with the spatula.
