Heat oven to 200C/180C fan/gas 6. Toss the butternut squash with the oil, cinnamon and a pinch of salt. Roast on a parchment-lined tray for 25 mins.
Crumble the cooked bacon over the squash, add the blueberries and drizzle with the maple syrup. Return to the oven for 5 mins until the squash is caramelised and the blueberries look plump and juicy. Meanwhile, make your porridge. Top with the squash, bacon and blueberries, and drizzle with a little extra maple syrup.
