1. Preheat the oven to 200°C / gas mark 6. Arrange the red onion on a large baking tray, drizzle on ½ tsp of oil, sprinkle with salt and pepper and place in the oven for 10 minutes.

2. Mix together the Asian-style sauce ingredients in a small bowl and put to one side. Remove the tray with the onions on from the oven, and add the broccoli, mushrooms, courgette, peppers and asparagus. Arrange in a single layer and drizzle on the remaining olive oil. Sprinkle on a pinch of salt and pepper and place back in the oven for 10 minutes.

3. Remove the tray from the oven and drizzle the Asian-style sauce over the vegetables. Toss everything together, then sprinkle on the cashews and sliced chilli.

5. Place back in the oven for a final 5-10 minutes until the sauce is bubbling and the vegetables are tender.

6. Serve with coriander-flecked boiled rice.
