Buffalo Chicken Calzone

Preheat the oven to 410 degrees F (210 degrees C). Grease a 12-inch pizza pan.

Place chicken into a large pot and cover with salted water; bring to a boil. Cook chicken in boiling water until no longer pink in the center and the juices run clear, about 15 minutes. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C). Transfer chicken to a bowl and shred with two forks.

Melt butter in a skillet over medium-high heat. Cook and stir shredded chicken and Buffalo wing sauce in hot butter until chicken is coated and heated through, 2 to 4 minutes.
