Roasted cheese & sage onions

Heat the oven to 200C/180C fan/gas 4. Peel the onions and slice them in half across the circumference. Put them cut-side up in a small baking dish and drizzle with 2 tbsp of the olive oil, then season with salt and pepper. Roast for 30 mins. Meanwhile heat the stock and add the miso and maple syrup. Grate the cheese into a separate bowl, then mix in the breadcrumbs and chopped sage.
