In an oven-proof skillet, heat 1 tbsp coconut oil over medium high heat. Add the diced sweet potatoes and saute until they have softened and begin to brown, about 12-15 minutes. About five or six minutes in, add the diced onion. Add the mushrooms and saute for about five more minutes. While that is working, beat six eggs, add the seasonings in with the eggs. Turn off the heat, add the baby spinach and toss until slightly wilted. Add the eggs and cheese to the pan and mix together. Place into a 375° oven and bake for about 10-12 minutes or until eggs are fully set. Let cool for about 5 minutes before cutting.
