Sauté ground beef in a large skillet over medium heat.

Add chopped onion and bell pepper to the skillet and continue to sauté until softened.

Season with salt and pepper.

In a separate bowl, mix cornbread mix, creamed corn, and egg.

Pour half of the cornbread mixture into a greased square Pyrex dish.

Spread the sautéed meat mixture evenly over the cornbread layer.

Sprinkle chopped jalapeno peppers over the meat mixture.

Top with Cheddar and Mozzarella cheese.

Pour the remaining cornbread mixture over the cheese layer.

Bake in a preheated oven at 375°F (190°C) for 45 minutes to 1 hour, or until golden brown and cooked through.

Let cool slightly before serving.
