I make them in a muffin tray... so they're bigger than tiny ones iykwim!
I use a glass to cut out puff pastry, then stretch it slightly to line the muffin tray (make sure you spray the muffin tray first)
Put any ingredients you want in a bowl.... i usually do ham, cheese, onion, mushrooms, capsicum, corn, fresh tomato any combination of the above! Mix it all together then spoon in to pastry. In a bowl whisk together eggs and a dash of milk... I'd do say six eggs for a dozen mini quiches... add salt and pepper then pour into prepared quiches. Bake in a 180 oven until set and browned.

They freeze well too

Can you tell that I don't actually follow a recipe!
