Mix rice together with chili powder, cumin and garlic salt. Add remaining ingredient except for cheese and sour cream. Sprinkle cheese over tortillas, leaving 1/2-inch border around edges, then arrange chicken and rice mixture down the center of each tortilla. (Optional: on some of the wraps, I dotted the cheese with about 1-2 tablespoons of reduced fat sour cream before arranging chicken and rice mixture down the center – it made the wraps delightfully creamy.) Roll stuffed tortillas, leaving edges open. Spray the tortillas all over with cooking spray.
Heat a large non-stick skillet (or griddle) over medium heat for 1 minute. Arrange 2 wraps, seam-side down, in pan and cook until golden brown and crisp, about 2-3 minutes per side. Transfer to a plate and repeat with remaining wraps. Serve.
