In a bowl, mix the chopped fish, egg, zucchini, carrot, green onion, soy sauce, sesame oil, salt, and pepper until well combined.

Heat oil in a frying pan over medium heat.

Scoop a portion of the mixture and flatten it into a pancake shape in the pan.

Cook for about 3-4 minutes on each side or until golden brown.

Repeat with the remaining mixture, adding more oil as needed.

Serve hot with dipping sauce if desired.
