Cook the Bacon and Beef: Preheat your oven to 400°F. In a large oven-safe skillet (about 4 quarts), cook the bacon and ground beef together over medium heat until the beef is browned, about 7-9 minutes. Do not drain the grease. If you do not have an oven-safe large skillet, you can transfer the beef to a casserole dish for Step 5.
5-6 slices bacon, diced, 1 pound ground beef
Sauté the Vegetables: Add the onion and bell pepper to the skillet. Cook for 3-4 minutes, until softened. Stir in the minced garlic and taco seasoning, cooking for another minute.
1 yellow onion, diced, 1 bell pepper, diced, 8 cloves garlic, minced, 1 packet taco seasoning
Add the Wet Ingredients: Stir in the diced tomatoes, tomato sauce, green chiles, barbecue sauce, Worcestershire, and pinto beans. Scrape any brown bits off the bottom of the skillet. Bring the mixture to a simmer and cook for 5-7 minutes to allow the flavors to meld. Season with salt and pepper to taste. Remove from heat.
1 14.5-ounce can diced tomatoes, 1 15-ounce can plain tomato sauce, 1 4-ounce can green chiles, 2 Tablespoons barbecue sauce, 1 Tablespoon Worcestershire, 1 15-ounce can pinto beans, drained & rinsed
Prepare the Cornbread Topping: While the beef mixture simmers, in a medium bowl, combine the Jiffy corn muffin mix, egg, milk, corn, and half of the shredded cheddar cheese.
1 package Jiffy corn muffin mix, 1 large egg, 1/3 cup milk or buttermilk, 1 15-ounce can corn, drained, 8 ounces sharp cheddar cheese, shredded
Assemble the Casserole: Spread the cornbread mixture evenly over the beef. Sprinkle the remaining cheddar cheese over the cornbread.
Bake: Bake for 18-20 minutes, or until the cornbread is golden brown and cooked through. Serve warm.
