Add the chopped onion, bell peppers, and jalapeño (if using) to the skillet. Cook for 5-6 minutes, stirring occasionally, until softened. Stir in the garlic and cook for an additional minute. - Build the Sauce
Mix in the fire-roasted tomatoes, Worcestershire sauce, paprika, oregano, basil, and a pinch of salt and pepper. Simmer for 5 minutes to allow the flavors to meld. - Combine with Rice
