For the chicken: Season the chicken breasts with salt and pepper. Then, place the chicken breasts in a medium saucepan with the garlic clove and a generous pinch of salt. Cover with water.
Bring to a boil over medium heat, then add the chicken. Reduce the heat to low and poach for 15–20 minutes, or until the chicken is cooked through (internal temperature of 165°F / 74°C). Remove the chicken and let rest until cool enough to handle, then shred or dice it.
To make the buffalo dressing: In a small bowl, whisk together the buffalo wing sauce, olive oil, honey, and apple cider vinegar. Test and adjust seasoning to taste.
Prepare the salad: In a large bowl, combine the romaine, arugula, carrots, celery, cucumber, tomatoes, green onions, cilantro, and chives. Add the chicken and toss gently.
Finally, drizzle the buffalo dressing over the salad and to to coat. Top with crumbled blue cheese and serve with a side of blue cheese dressing.
