Here's how to make mushroom quiche with a sausage crust:

Add olive oil and butter to a large frying pan and heat over medium heat. Add onions and cook for 2 minutes. Add mushrooms and cook for 10 minutes.

Use your hands to mix together sausage and coconut flour. Press it into the bottom of a pie pan as you would a crumble crust.

Bake the crust for 6-8 minutes until browned all over. Pat the grease away with a paper towel.

Add eggs, cream, and water to a large bowl. Use an electric mixer to beat together until light and frothy.

Add half of the cheese to the bottom of the pie crust evenly.

Put mushrooms and onions on top.

Cover with the remaining cheese.

Pour the egg mixture evenly on top.

Bake for 45 minutes. At minute 25, lay a piece of tin foil on top of the quiche to stop it from browning too much.

And enjoy!
