Let’s bring these flavors to life with some simple steps:

1. Preheat your oven to 375°F (190°C). While it warms up, slice the tops off the bell peppers and remove the seeds and membranes.
2. In a large skillet, heat olive oil over medium heat. Add the chopped onion and garlic, sautéing until they’re fragrant and translucent, about 3-4 minutes.
3. Add the ground beef to the skillet. Cook until browned, breaking it up with a spoon as it cooks. This should take about 6-8 minutes.
4. Stir in the ketchup, mustard, Worcestershire sauce, cooked rice, salt, and pepper. Mix well to combine all the flavors. Allow this to simmer for an additional 2 minutes.
5. Remove the skillet from heat and stir in half of the shredded cheddar cheese.
6. Fill each bell pepper with the beef mixture, packing it gently to ensure they’re well-stuffed.
7. Place the stuffed peppers in a baking dish. Cover the dish with aluminum foil and bake in the oven for 30 minutes.
8. Remove the foil, sprinkle the remaining cheese over the peppers, and return them to the oven for another 10 minutes, or until the cheese is melted and bubbly.
9. Once cooked, allow them to cool slightly before serving.

These steps will guide you to a dish that’s as inviting as a Southern summer evening. Just remember, cooking is as much about instinct as it is about following a recipe. Trust your senses!
