Preheat oven to 350 degrees F
Over medium heat, warm your skillet, melt ghee, add olive oil, mushrooms and onions, a large pinch of salt, and gently mix
Cook for 20 minutes, until the mushrooms start to brown, and the onions are transluscent and soft
Add in the coconut aminos, garlic powder, and pepper, gently mix - the sauce will start to thicken once it's ready, about 10 more mintues
Once the mushrooms and onions have finished carmalizing, carefully spread them on the bottom of the skillet, turn off the heat, and add the egg mixture - do not mix
Transfer to the oven and bake for 12-14 minutes
Remove from the oven, and allow to sit for 5 minute before slicing
Garnish with scallions
