Preheat oven to 350F and grease 9-inch pie dish.
In a medium sized bowl, mix together all crust ingredients until ball forms.
Press crust into pie dish evenly. Bake for 15-20 minutes or until slightly golden brown.
While crust is baking, saute onions and turkey bacon in olive oil on medium-high heat. Once cooked through, add in spinach until wilted. Turn off heat and let cool.
In a large bowl, whisk together eggs, milk, 1/2 cup cheese, salt and pepper.
Add in turkey bacon mixture and pour into slightly cooled crust. It can still be warm, just not hot.
Add the remaining cheese on top and bake for 35-40 minutes or until no longer jiggly. A knife inserted into the center should come out clean.
Let cool 20 minutes before cutting into it.
Enjoy!
Store leftovers in the fridge, covered in foil.
