Mix together the chicken, mirin, tamari, ginger, garlic, lime juice and cashews. Use your hands to form small patties.
Bring a large saucepan of water to the boil. Add a steamer insert and steam the bok choy and broccoli for a few minutes until they begin to wilt.
Drizzle steamed vegetables with a little sesame oil and lime juice.
Heat the sesame oil in a frying pan and cook patties for around 3 minutes on each side, or until they are cooked through.
Serve patties with the green vegetables.
