The luxurious feel of this dish hides the fact that it’s also a one-pan wonder that you can knock up in less than half an hour

This is one of my favourite types of dishes: a quick cook, quick carb, where the sauce takes as little time to make as the pasta. Broccoli and blue cheese are a classic combination, and with the crunch of hazelnuts and the creamy sauce, this feels like a special dinner, even though it takes just minutes to pull together. It serves two generously – we stretched it to three at lunchtime, so you may have enough for a lunchbox the next day.
