Preheat oven to 350 degrees.
In a large pan, heat butter in frying pan.
Pat chicken breasts dry, butterfly and cut in half.
Generously season on all sides with salt, pepper, garlic powder, and italian herbs.
When butter is melted and foamy, add chicken to pan and brown on all sides, about 4 minutes per side.
While chicken is browning, lay parchment on baking sheet.
When chicken is browned, remove from pan.
