Clean the fish and finely make zebra stripes on it with a knife. Blend small onions, garlic cloves, black pepper powder, turmeric powder, chilli powder and salt. Make a good paste. Now carefully fill this paste into the fish. Also add herbs into this. Keep the fish aside for around 10-20 mins.
Pre-heat the microwave (750W). Take a microwave vessel and pour little bit oil on it. Spread it well. Layered the fish into this and pour the remaining oil over it. Cook this for around 20-25 min. After 15 min turn the fish carefully and cook this for the remaining time.
Place the fish into a nice plate and add 4-5 drops of lemon over it. Decorate with sliced tomato, green chilly, onions and coriander leaves.
Enjoy this with hot rice.
