Start by heating your large pot or Dutch oven over medium heat. Add the ground beef and cook until browned, stirring occasionally to break it apart.
Once the beef is nearly cooked through, add the chopped onion, minced garlic, and red bell pepper. Sauté for about 3-4 minutes, until the vegetables are softened and fragrant.
Stir in the uncooked orzo, taco skillet sauce, and chicken broth. Season with salt and pepper to taste, and add the hot sauce for an extra kick. Give everything a good stir to combine all the flavors.
Bring the mixture to a gentle simmer. Cover the pot and reduce the heat to low. Allow the orzo to cook for about 10-12 minutes, or until the pasta is tender and has absorbed most of the liquid. Stir occasionally to prevent sticking.
Once the orzo is cooked, remove the pot from the heat. Sprinkle the shredded cheese over the top and cover the pot again for a few minutes to let the cheese melt beautifully into the dish.
Give the orzo a gentle stir to incorporate the melted cheese. Serve it warm, garnished with chopped tomatoes, olives, green onions, and fresh cilantro for a burst of color and flavor.
