The Bento Buster, a Kiwi in Japan, shows how to made a New Zealand Bacon & Egg Pie - It's a Kiwi classic! To bake the pie in the the oven, prepare it as in the video in a pie dish then back at 200c for 25 - 30 minutes or until the pastry is flaky and golden brown. I used a Japanese pie maker called My Bistro (only $12)
Ingredients:
Puff pastry pie sheets
eggs
mushrooms
green peas
slices of bacon
finely chopped green onion
pepper to taste

Egg wash
beat 1 egg and 1 Tbs water
