This will make two large pies!
Directions: Preheat oven to 350ºF
Using a large skillet over medium-high heat add your four tablespoons of butter.
Add your spinach and sauté until fully wilted.
In a separate bowl, whisk your eggs together.
Add your cottage cheese and cheddar cheese to the eggs and combine well.
By this time, your spinach should have cooled down slightly, it can still be pretty hot when you add it, so just dump in into your egg and cheese mixture.
Combine well.
Get two pie dishes and grease them with olive oil or butter.
Evenly distribute quiche mixture into pie dishes (store in airtight container in the refrigerator, if baking the next day)
Bake until the top is a golden color and it is stiff to the touch.
