Saute peppers and onions in a skillet with coconut oil
While the meat is cooking, slice the sweet potatoes into 1/2 inch thick circles and line them into a 9 by 13 baking dish. Sprinkle with salt and pepper.
Add the spinach to the top of the sweet potatoes and then pour the sausage and veggies over top of the spinach and potatoes.
Whisk the 12 eggs, rosemary, salt, and pepper together in a large bowl, pour over top of the veggies and meat.
Cover the dish and stick it in the refrigerator overnight. Or if you aren't making it ahead of time, you can bake it right away. I have done it both ways and either way is delicious.
In the morning, bake it in a 375-degree oven for 45 minutes or until the eggs are set.
