Step 1 Preheat oven to 230C. Combine half the oil, mandarin rind, mandarin juice, cinnamon, ginger and salt in a small bowl.
Step 2 Place the pork in a large roasting pan. Pour over the oil mixture and rub into pork rind to coat. Roast for 30 mins.
Step 3 Reduce oven to 180C. Transfer the pork to a plate. Place the sliced mandarin in the pan. Top with the pork. Roast for 1 1/2 hours or until the pork is cooked through. Set aside, covered, for 10 mins to rest.
Step 4 Meanwhile, steam, boil or microwave the cauliflower, broccoli and beans separately until tender. Combine the cooked vegetables in a large bowl with the garlic and remaining oil. Season.
Step 5 Thickly slice the pork. Sprinkle the vegetable mixture with coriander to serve.
