In a bowl, mix the pomfret pieces with lemon juice, tomato paste, salt, onion powder, garlic powder, and chili powder until the fish pieces are evenly coated with the spices.

Heat oil in a frying pan over medium heat.

Once the oil is hot, add the seasoned pomfret pieces to the pan.

Fry for about 3-4 minutes on each side, or until they are golden brown and cooked through.

Transfer the fried pomfret pieces to a serving dish.

Just before turning off the heat, add the sliced green chili to the pan and cook for about 1 minute to release its flavor.

Use the cooked green chili as a garnish over the fried pomfret pieces.

Serve hot.
