Preheat oven to 400 degrees F.
Mix together 2 packages muffin mix with 2 eggs, 4 tablespoons melted butter (melt in microwave 30 seconds), 1 1/2 cups milk and frozen corn kernels. Wipe a nonstick skillet with a little extra or vegetable oil and pour in the muffin mix. Use a large skillet, 10 to 12 inch. Choose a pan with oven safe handle or, double-wrap handle with foil to protect it in the oven. Place pan in oven and bake 12 to 15 minutes in center of the oven until light golden in color.
Brown the meat over medium high heat in a second skillet in extra or vegetable oil, 2 turns of the pan. Add onions and spices and cook meat 5 minutes more.
Remove cornbread from oven and top with meat, cheese, and veggies. Add pan back to oven and cook 5 minutes more to melt cheese. Garnish with cilantro, optional. Cut into 8 wedges and serve the deep dish pan pizza from the skillet. Pass taco sauce at the table to sprinkle on top.
