Preheat oven to 400 degrees.
Crumble turkey in a large skillet and stir cooking over medium heat until browned.
While the turkey is cooking mix the corn muffin mix, 1 egg, can of creamed corn, 1/2 cup of shredded cheese, and milk in a large bowl. Stir until combined then let sit.
Drain grease from turkey, turn heat down to med low then add Manwich Sloppy Joe Sauce. Let is warm and come to a simmer.
Spray a 8X8 baking dish with cooking spray then pour sloppy joe mixture into dish. Top with the cornbread mixture.
Add 1/2 cup shredded cheese (you can never be too cheesy, right?) on top and pop in the center of the oven.
Bake for 25 minutes or until the cornbread is cooked through and golden.
I take my dish out of the oven, add a sprinkle of more cheese, and bake for another 2 minutes until melted.
Let cool slightly then cut into squares and serve.
