Substantial enough for any meal of the day! A flaky pie crust is oven-baked with a filling of eggs, cheeses, spinach, bacon, mushrooms, and seasonings. Remember, ingredients can always be omitted to make it just right for you! Available only in a 6 serving size, but leftovers reheat wonderfully. You can also make individual quiches in a muffin pan using only the filling, making it keto-friendly and gluten-free.
