Garlic bread hot dog with cheesy rosemary & truffle fries
Heat a large, wide-based pan (preferably non-stick) with a drizzle of olive oil over a medium heat. Once hot, add the onion and half the balsamic vinegar with the sugar and a pinch of salt. Reduce the heat to low and cook for 10-12 mins until softened and caramelised. Set aside.
