Hot turkey and caramelised onion tart with melting Stilton cheese

If you like pizza, you’ll love this onion tart recipe by Adam Gray. It's a quick and easy turkey and caramelised onion puff pastry tart inspired by Christmas leftovers. Simply omit the turkey if you want to make the tart vegetarian — virtually all Stilton is vegetarian. You don’t have to use Stilton cheese either – try Gruyère or Lancashire instead.
