This started as a cheap dinner for two but now it's become a staple part of our regular weeknight family meals. The idea is to roast sweet cherry tomatoes and garlic until their flavour intensifies and then press together with a fork in the roasting tray to create the perfect coating for freshly cooked pasta. In this version, we make our own pici, one of the easiest pastas to make which can be made in the time the sauce cooks.
