In a large cast iron skillet pan over medium high heat cook your meat until it is no longer pink. You could add finely diced onions too so they soften slightly together. Drain grease and set aside. Preheat oven to 350 degrees F.
Spray round pie pan with non stick spray, or use 8x8 dish. Pour diced tomatoes, beans, and seasonings in with the meat. Stir to combine and transfer to the prepared pie plate.
In a bowl, combine the Jiffy cornbread mix with necessary ingredients to make batter; egg, and milk until well blended. Spoon the cornbread batter over the chili mix and spread in an even layer. Bake for 25 to 30 minutes or until top is golden brown and cooked thru.
