Heat a large cast iron skillet over medium-high heat. Add meat, and cook, crumbling and stirring, until browned.
Add onion and saute until translucent. Add seasoning, beans, and tomato paste, stirring until well combined. Add in tomatoes and water. Simmer 10 minutes, stirring occasionally.
Meanwhile, preheat oven to 400°F and prepare cornbread mix to package directions.
When ready, pour batter onto chili and smooth over with a spoon. Bake for 20-25 minutes or until a toothpick placed in the center of the cornbread comes out clean.
