Heat a cast iron dutch oven over medium-high heat with the avocado oil until it hot in the pot.
Evenly spread the ground turkey over the bottom of the pot and allow it to brown on that side without stirring.
Add your spices, salt and pepper so that they can toast as you brown your turkey.
Stir the turkey and allow to brown on the other sides (about 5-7 minutes)
Create a well in the center of your turkey and add the onion and celery.
Saute the onion and celery with the turkey until softened (about 4 minutes)
Add tomato paste or powder and stir to combine well. Scrape any brown bits from the bottom of the pot.
Add the corn and beans and stir to combine.
Add the ketchup and mustard and stir to combine.
Add the tomatoes and broth and stir to combine.
Add the maple syrup (or brown sugar) and stir once more.
Reduce the heat to medium low to simmer.
Taste the chili and add any seasonings as needed. You might need more salt at this point.
Allow to simmer over medium low for 30 minutes.
Preheat the oven to 425°
Bake for 12-15 minutes or until golden brown.
Serve with green onions, sour cream, and shredded cheese. Enjoy!
