In a deep skillet or dutch oven heat 2 tbsp of coconut oil over high heat
Add your ground turkey and break up with a wooden spoon and season with salt, pepper, and poultry seasoning
Put your sweet potatoes in a pot, cover with water, cover pot, bring to a boil and cook until done, depending on the size of your cubes but should be about 12 minutes
You should still be stirring your ground turkey, now add in the onions and carrots and cook for another 5 minutes
In a small saucepan on another burner over medium heat, melt 2 tbsp of your ghee and once melted whisk in your arrowroot powder. Whisk for about a minute and then add your chicken stock. Season with salt and pepper and let thicken for a few minutes
Take your turkey off of the heat and drain all the excess oil out.
Put your skillet or dutch oven back on the heat and stir in the gravy
Next stir in your frozen peas and turn the heat off, let sit in pan for a couple minutes while you prepare the potatoes
Drain the potatoes into a colander and leave them there while you return the pan to the heat and melt your remaining 2 tbsp of ghee
Peel and slice your banana and throw it in the melted butter, now add your sweet potatoes on top and using a masher, mash them to the consistency of your liking
Put your turkey mixture into the bottom of a 9x13 casserole dish if you didn't use a dutch oven
Now spread your mashed sweet potatoes evenly over the top of turkey mixture
