Sausage & Egg Breakfast Casserole

0 Heat a medium to large size pan. Once it's hot add butter. Then add your ground sausage. Season with a sprinkle of sea salt and black pepper. Break it up and let it cook for a few minutes until no longer pink.
2 Then add in the spinach and let it wilt down. Set aside or remove from the pan and let cool.
1 In a medium mixing bowl, add in eggs, milk, cheese, 1 tsp sea salt and ½ tsp pepper.
3 In a 9x13 pan, add the sausage on the bottom and make sure it's cooled. Add the chopped bread on top. Pour the egg mixture over top and mix everything together.
4 Cover with plastic wrap or foil and let it soak in the fridge for 1-24 hours. The longer the better! 
5 Preheat your oven to 350F degrees. Remove the pan from the fridge and let it sit at room temperature for 30 minutes before cooking. Put in the oven and back for 40-45 minutes until it's set.
6 Let cool, slice and eat! To serve, reheat and enjoy!
