Heat large nonstick skillet over medium heat until hot. Add Ground Beef; cook 8 to 10 minutes, breaking into small crumbles and stirring occasionally. Remove from skillet with slotted spoon; pour off drippings. Return to skillet; stir in pepper sauce. Cook and stir 1 minute or until heated through.
Cook's Tip: Cooking times are for fresh or thoroughly thawed Ground Beef. Ground beef should be cooked to an internal temperature of 160ºF. Color is not a reliable indicator of ground beef doneness.
Meanwhile, heat taco shells according to package directions.
Evenly spoon beef mixture into taco shells. Add lettuce; drizzle with dressing. Top evenly with carrot, celery and cilantro. Garnish with carrot and celery sticks or cilantro sprigs, if desired.
