If the thought of sweating over several pots and pans and then having to wash up half of the cookware you own fills you with dread, a meal chucked in a single roasting tray or dish is the answer. And that has never been more relevant than now, when we have to cook pretty much all of our meals at home (and do all the washing up too). From elaborate special occasion dinners to speedy weeknight meals, you'll be surprised by the variety of dishes you can cook in your roasting tray.
