Prep your pie crust.
Preheat your oven to 400 degrees F.
As the oven is preheating, prep your mushrooms, onions and spinach.
Place the mushrooms and onions in separate areas on a sheet pan and sprinkle with olive oil, salt and pepper. Mix gently to coat and roast for fifteen minutes. Now, add the spinach (also drizzled with olive oil and sprinkled with salt and pepper) to the baking sheet in its own area and roast all vegetables for another five minutes.
While the vegetable are roasting, make your filling by combining the eggs, blended cottage cheese, cheddar cheese, salt pepper and spices.
When the vegetable are roasted, reduce the heat on your oven to 375 degrees F.
Combine the filling with the mushrooms and spinach and pour into your crust.
Use the roasted onions to decorate the top of your quiche as shown.
Bake the quiche at 375 degrees F for approximately 40 minutes or until the edges are set and it is just slightly jiggly in the centre. Allow to rest for 10-20 minutes. Serve and enjoy!
