Step 1 Preheat oven to 200°C. To make meatballs, place chicken in a food processor and pulse until finely chopped, taking care not to mix it to a paste. Mix soy sauce, sesame oil, coriander and breadcrumbs into chicken. Shape mix into small walnut-sized balls. Place sesame seeds on a flat plate and roll meatballs in seeds until lightly coated. Place balls in an ovenproof dish and bake for 15-20 minutes until cooked through.
Step 2 Arrange pumpkin in a single layer on a lined baking tray, season with salt and pepper and drizzle with a little olive oil. Roast for 20 minutes, turning at times, until pumpkin is just tender.
Step 3 While pumpkin and chicken balls are cooking, cook rice following packet directions.
Step 4 To make salad, segment mandarins and mix with roasted pumpkin and spinach. Combine lemon juice, honey and oil in a small bowl and drizzle over salad. Gently toss to combine.
Step 5 To make miso rice, mix miso, soy sauce, coriander and spring onions into cooked rice. Serve meatballs with miso rice and salad. Add a drizzle of sweet chilli sauce if you prefer.
