Fill a 3 to 3.5-quart sauce pan full of water. Add the chicken breasts and garlic clove. Bring to a full boil and then turn off the heat and cover the pot. After 12 minutes, remove one of the breasts and cut into the thickest part to check to see if they are done (they should be cooked through and register at least 165°F on an instant-read thermometer). If there is any pink, return to the pot for another 15 minutes. Drain chicken through a colander, discard the garlic clove and cool slightly.

Chop or shred the chicken into small pieces. Add the chicken and onion to a large bowl and set aside. In a small bowl, whisk together the yogurt, barbecue sauce, honey, salt, pepper, garlic powder and cayenne pepper. Add the yogurt mixture to the large bowl with the chicken mixture and toss well to combine. Add more barbecue sauce, as desired. Serve on bread with sliced pineapple and greens or layer over a salad. Serve immediately or store chicken salad in a sealed container in the refrigerator for up to three days. Enjoy!
