In a shallow bowl combine yogurt, honey, dijon, garlic powder and salt. Place chicken in bowl and cover with marinade. Set aside.
To food processor add: pecans, panko, fresh rosemary, salt and garlic powder. NOTE: If you prefer you can simply finley chop with a knife. Pulse in food processor until fine being careful to not over process.
Pour the nut mixture on to a shallow plate. Remove some of the marinade from the chicken. Press the chicken into the nut mixutre until fully covered on both sides.
