If you have cooked chicken, skip this step. If you need to cook the chicken, preheat the oven to 400℉ (200°C). Line a small baking sheet with parchment paper. Coat the chicken in olive oil and season with salt and black pepper. Bake in the preheated oven for 25 minutes or until internal temperature reaches 165℉ (75°C). Let the chicken cool and shred.
While the chicken is baking, chop the red onion, fresh herbs, and capers. Add the dressing ingredients including the yogurt, Dijon, lemon, and seasonings to a large bowl and whisk to combine. Add the other ingredients to the bowl and mix so everything is well coated by the dressing. Give it a taste and add more salt as needed.
