Preheat oven to 400F.
In a large nonstick pot, cook turkey and optional onion, breaking the turkey into crumbles, until cooked through.
Add seasonings to turkey & mix.
Stir in tomatoes & beans.
Simmer uncovered for 20–30 minutes, stirring occasionally, until THICK.
Combine all cornbread ingredients until combined.
Transfer HOT chili to a deep 9x13 in baking dish, leaving room for the topping to rise.
Spoon batter evenly over the chili and gently spread. Don’t mix it in!
Bake 25 min, until the cornbread is set and a toothpick inserted into the cornbread layer comes out without wet batter.
Rest 10 minutes, then scoop & enjoy!
