Brown Sausage. Place butter in 13x9 pan and warm in oven to melt, take out of oven. Chop spinach until very fine and blot out water with a towel.
Beat eggs with mixer until frothy then add milk and all other ingredients and stir until mixed.
Pour in 13x9 with butter and bake at 350 degrees for 35 minutes or lightly browned on top. Cool slightly and cut into squares.
Notes: I like the gluten free. I still used the baking powder. I use any left over cheese in the fridge as my sister suggested. Colby Jack is good. Also I used Jimmy Dean sausage but my sister uses a turkey sausage. Enjoy.
