Adapted from Huey's recipe for Mini Leek Tarts, which he has classified as a SNACK ATTACK recipe. Huey (Iain Hewitson) is an Australian chef: he has written several cooking books and hosts a popular TV cooking show each weekday. If you preferred, you could use this recipe to make one larger tart, but if you do this, remember to adjust the cooking times. I have added onion and garlic to Huey's original recipe as the combination of leeks, onions and garlic - if you have not tried it - is truly delicious. Australian Tasty Cheese is a yellow, fairly flavoursome cheese used a lot in cooking. Vary the cheese to suit what's on hand and your taste preferences.
