Heat oil in a large skillet over medium-high heat. Add onion and bell peppers and cook until softened. Stir in chicken, garlic, Worcestershire sauce, salsa, and TABASCO® Sauce and heat through. Add salt to taste and keep warm.
For each fajita, cover three quarters of a tortilla with a generous serving of chicken mixture, 1/4 cup cheese, and 1/4 cup rice. Roll up and serve.
