If desired, partially freeze beef for easier slicing. If using steak, trim fat from meat and thinly slice steak across the grain into bite-size strips . Place meat strips in a deep bowl. Sprinkle with 2 teaspoons of the fajita seasoning. Cover and chill 30 minutes.
Wrap tortillas tightly in foil. Heat in a 350 degree F oven about 10 minutes or until heated through. Meanwhile, in a 12-inch skillet heat 1 tablespoon of the oil over medium-high heat. Add sweet pepper, onion, and remaining 1 teaspoon seasoning. Cook and stir about 3 minutes or until crisp-tender. Remove onion mixture from skillet.
Add remaining 1 tablespoon oil and the meat to the skillet. Cook and stir for 2 to 3 minutes until desired doneness for steak or until chicken or turkey strips are no longer pink. Drain well. Return onion mixture to skillet. Stir in tomato. Cook and stir for 1 minute or until heated through. Remove skillet from heat; stir in lime juice.
To serve, fill warm tortillas with meat mixture. If desired, top meat mixture with guacamole, salsa, and sour cream. Roll up tortillas. Serve with lime wedges.
