Chop the carrot, shiitake mushrooms, and onion finely. Slice the green onion thinly. Prepare 3-4 tbsp cornstarch and 1 egg.

Drain the tofu and mash it thoroughly.

In a bowl, mix the mashed tofu, chopped vegetables, egg, salt, sesame oil, black pepper, and cornstarch. Combine well.

Heat a pan over medium-low heat and add a suitable amount of cooking oil. Shape the mixture into patties and pan-fry until golden brown on both sides.
