Prepare your mise-en-place! Meaning prepare all of your ingredients, spices, meat, mince the vegetables etc…
In a large pan, heat a little avocado oil (or other high-heat oil) and add onion, garlic, celery and carrot. Sauté until translucent. 2-3 mins
Add ground chicken and cook while breaking it up with a wooden spoon.
When chicken is about cooked, add salt, garlic powder, cayenne, smoked paprika and worcestershire sauce and stir into the meat to incorporate.
Let the spices cook for around 30 seconds.
Then add the broth. Add a good sprinkling of flour and stir in to thicken slightly (this makes it slightly like gravy)
When the meat has soaked up the liquid but still very moist, stir in the tomato sauce.
Mash cooked sweet potato with some ghee or butter, taste for salt and adjust if necessary.
At this point the meat should be moist but not watery. Add to a lightly greased baking dish. (mine was a 9×11 oval baking dish)
Layer with corn, then layer with sweet potato mash
Smooth the potatoes with the back of a spoon to even it out then if you want, drag a fork down the length, all the way across to create little ridges that will crisp up when baked.
