Another Quick Tart - Leek & Gorgonzola

Pre-pub. My wallet has no desire to eat out and I have no desire to wake up with a raging hangover tomorrow (that's your 30s for you...) so eating in before going out is the order of the day. A Leek & Gorgonzola Tart in this case.
You know the drill. Sweat a member of the onion family to softness with a herb of choice (thyme perhaps) and bake it on a sheet of puff pastry with lumps of cheese. Eat and go to the pub safe in the knowledge that you have ballast onboard.
