Give me a nutty sloppy cornbread recipe

For the Cornbread:

1 cup cornmeal

1 cup all-purpose flour

1/4 cup sugar

1/2 teaspoon salt

1 cup milk

1 tablespoon baking powder

1/4 cup vegetable oil

2 large eggs

1 cup chopped nuts (pecans or walnuts work well)

For the Sloppy Joe Filling:

1 lb ground beef or ground turkey

1 small onion, finely chopped

1 small green bell pepper, finely chopped

1 cup ketchup

2 tablespoons brown sugar

2 cloves garlic, minced

1 tablespoon Worcestershire sauce

1 tablespoon mustard

1 teaspoon chili powder

Salt and pepper to taste

In a large skillet, cook the ground beef (or turkey) over medium-high heat until browned. Drain any excess fat.
Add the chopped onion, bell pepper, and garlic to the skillet. Cook until the vegetables are soft, about 5 minutes.
Stir in the ketchup, brown sugar, Worcestershire sauce, mustard, chili powder, salt, and pepper. Reduce the heat and let the mixture simmer for about 10 minutes, stirring occasionally.

Preheat your oven to 400°F (200°C). Grease a 9×13-inch baking dish or a similarly sized cast-iron skillet.
In a large mixing bowl, combine the cornmeal, flour, sugar, baking powder, and salt.
In another bowl, whisk together the milk, vegetable oil, and eggs.
Pour the wet ingredients into the dry ingredients and mix until just combined. Fold in the chopped nuts.

Pour half of the cornbread batter into the prepared baking dish or skillet, spreading it evenly.
Spoon the sloppy joe filling over the cornbread batter, spreading it evenly.
Pour the remaining cornbread batter over the sloppy joe filling, spreading it to cover the filling completely.
Bake in the preheated oven for 20-25 minutes, or until the top is golden brown and a toothpick inserted into the cornbread comes out clean.
