Cook the bacon until crisp and chop. I do a whole pound in the oven and only use 1/3 for the recipe.
Grease a pie plate or 8x8 glass dish. Preheat oven to 350 degrees F.
Thaw the spinach and squeeze dry. Slice the onion very thinly into half rounds or mince. Grate the cheese.
Put all of the ingredients into a large bowl and mix with a hand mixer until totally combined. Pour into the prepared pan and spread with a rubber spatula. Place into the middle of the oven and cook for 40 minutes.
Serve warm. Refrigerate up to 1 week or freeze up to 3 months.
Serves 6 at 4 net carbs per person.
UPDATE: 2/28/18 - I changed my nutritional calculator from the MasterCook Cookbook program to Fatsecret[dot]com. I entered the ingredients into Fatsecret and changed the serving size from 8 servings to 6. I updated the nutritional information accordingly.
