Preheat the oven to 325F.
In a cast iron pan, combine the ingredients for the Maple Breakfast Sausage over medium-high heat. Crumble the sausage and cook for about 5 minutes.
Add the mushrooms and leek to the pan and continue cooking for another 5 minutes.
Meanwhile, whisk together 10 eggs with the salt in a large bowl. Set aside.
Once the veggies are soft and the sausage cooked through, transfer all the contents to a bowl with a slotted spoon. Cover the bowl to keep warm.
Add ghee to the pan and melt.
Evening sprinkle the shredded sweet potatoes in the bottom of the pan to create the crust. Cook for about 3 minutes.
Carefully add the sausage mixture back to the pan and spread out evenly.
Pour the whisked eggs over the top.
Transfer the pan to the oven and bake for 20-25 minutes, or until the eggs are cooked through.
