BBQ Chicken Tacos

Preheat an outdoor grill for medium-high heat and lightly oil the grate.

Cook chicken on the preheated grill until no longer pink in the center and the juices run clear, 3 to 4 minutes per side. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C). Remove chicken from the grill and set aside until cool enough to handle.

Shred cooled chicken and transfer to a saucepan. Add BBQ sauce, onion, and chile-garlic sauce; stir until chicken is coated. Cook over medium-low heat, stirring often, until steaming, about 5 minutes.

Place a few spoonfuls of chicken mixture onto each tortilla and sprinkle with Cheddar cheese, black olives, and tomato. Roll up and serve.
