Roasted Summer Squash Quiche

Instructions

1. The plan ahead part (early in the day or day before):
2. Preheat oven to 425 degrees. Spread squash and leeks on a parchment-lined baking sheet in a single layer. Coat with olive oil and generously sprinkle with sea salt. Roast for 30 to 35 minutes until vegetables are just starting to brown.
3. Preheat oven to 375 degrees. Place rolled-out pie dough on a pie plate. Cover the pie with tin foil or parchment paper and fill with dry beans or pie weights. Bake for about 7 minutes. Remove from oven. Take beans or weights out and let pie crust cool a bit.
4. Line the bottom of the crust with roasted squash and leeks. Beat eggs and milk together in a large bowl. Add cheddar, Parmesan, thyme and salt and mix well. Pour over the top of the squash. Bake the squash quiche for about 50 to 60 minutes until a knife inserted in the centre comes out clean. 
5. Cool the squash quiche for at least 10 minutes before cutting.
