Make the Dressing: Blend all the salad dressing ingredients together in a blender or small food processor until smooth and creamy, and refrigerate until ready to use.
Cook the Chicken: Season the chicken breast with the marinade, keeping a tablespoon of oil for the skillet. Heat the oil in a skillet over medium-high heat. Cook the chicken until both sides are golden brown, about 3-4 minutes per side. Once cooked, remove from the heat, allow to rest for 10 minutes, then slice into strips.
Prepare the vegetables and place in a large salad bowl. Add the chicken strips on top. Pour the cilantro yogurt dressing over.
Toss well until all the ingredients are coated with the dressing.
Notes
Make Ahead: You can make the dressing up to a week in advance and you can prepare most of the salad up to 1 day in advance.
