Chop the enoki mushrooms into small pieces.

In a bowl, mix ground meat, chopped enoki mushrooms, fresh okara, salt, and pepper until well combined.

Shape the mixture into patties of equal size.

Heat salad oil in a frying pan over medium heat and cook the patties until golden brown on both sides and fully cooked through.

In a small bowl, mix yogurt, olive oil, salt, pepper, and chopped parsley to make the yogurt sauce.
