Prep the ingredients by dicing the onion and bell pepper, mincing the garlic, and measuring out all other ingredients.
In a large skillet over medium-high heat, add the ground beef and taco seasoning. Cook until browned, about 5 to 7 minutes, draining excess fat.
Add the diced onion and bell pepper to the skillet, stirring occasionally until softened, about 3 minutes. Mix in the minced garlic, salt, and pepper; cook for another minute.
Stir in the undrained diced tomatoes, chicken broth, white rice, and Worcestershire sauce. Bring to a boil, then reduce heat to low, cover, and simmer for 18 to 20 minutes until rice is tender.
Remove from heat and sprinkle shredded Cheddar cheese over the mixture. Cover for a few minutes to allow cheese to melt.
Garnish with freshly chopped parsley and serve hot.
