Brown Ground Meat: In a large ovenproof skillet (like a Dutch Oven) over medium-high heat, brown the ground meat. (You do not need to drain the excess fat after browning.)
Add Vegetables: Add chopped onion and bell peppers to skillet, stir, then sauté until tender, about 4-5 minutes.
Add Additional Ingredients: Add in and stir together diced tomatoes, tomato sauce, and Worcestershire sauce.
Add Rice and Broth: Stir in uncooked rice, making sure it's evenly distributed in the skillet, then pour in chicken broth.
Add Seasonings: Season with garlic powder, Italian seasoning, salt, pepper, cumin, and paprika. Stir to combine.
Boil then Simmer: Bring mixture to a boil, then reduce heat to low. Cover skillet with a lid and simmer for 15 minutes.
Scrape Bottom of Skillet then Cook Again: Remove lid, scrape up any rice that has stuck to the skillet, then cover again and simmer until rice is fully cooked, about an additional 10 minutes.
Remove Pot from Stovetop Burner: Remove pot from stovetop heat (it's OK if there is still some liquid in the pot). Carefully taste then adjust seasoning based on your preferences.
Add Cheese then Broil: Turn on oven broiler, then sprinkle shredded cheddar cheese on top. Transfer pot to oven under oven broiler and broil until cheese is golden and bubbling, about 1-2 minutes.
Garnish and Serve: Garnish with fresh parsley, then serve.
