Start by chopping or shredding the cooked chicken. If you’re using a rotisserie chicken, remove the skin and shred the meat with two forks. Chop the bell pepper, red onion, and cilantro, then drain and rinse the garbanzo beans and corn.
In a large mixing bowl, combine the chicken, garbanzo beans, corn, bell pepper, red onion, and cilantro.
In a small bowl, whisk together the Greek yogurt, lime juice, and taco seasoning until smooth.
Pour the dressing over the chicken and vegetable mixture, tossing everything together until evenly coated. Taste and adjust seasoning if needed. Serve immediately or chill for 30 minutes to let the flavors meld.
