1 tablespoon vegetable oil
1 tablespoon butter
1 pound skinless, boneless chicken breasts, cut into bite-size pieces
¼ cup hot sauce
4 (10 inch) flour tortillas
2 cups shredded lettuce
1 celery stalk, diced
½ cup blue cheese dressing
Heat oil and butter in a large skillet over medium-high heat until butter melts. Add chicken; cook and stir until no longer pink in the center and the juices run clear, about 10 minutes. Remove from the heat.
Pour hot sauce into the skillet and toss until chicken is coated.
Lay tortillas out on a work surface. Divide sauced chicken evenly among tortillas, top with lettuce and celery, then drizzle blue cheese dressing over top. Fold in tortilla sides and roll around filling.
