Meanwhile, cook ground beef in a skillet over medium heat, breaking it up with a masher or base of a wooden spoon and stir in taco seasoning until just brown.
While you're cooking the taco meat, bake taco shells 2-3 minutes.
Optional: combine sour cream and fiesta ranch mix for a topping.
Fill tacos with ground beef, shredded cheese and fiesta sour cream and any additional toppings.
