Blackstone Chicken Pesto Sandwiches

#1: ignore the ketchup and mustard in my picture. This is son's sammy. He's a newly hatched adult. #2: fire! I seasoned with s&p, paprika, gp & op, and a little herbs de prov. I put my pesto on the chicken, then added fresh motz and chucked under the broiler. 5 out of 5 approve.
