Take the butter out of the fridge and bring to room temperature.
Start with the herb butter. Mix all ingredients thoroughly in a small bowl and let sit until it’s time to serve.
Season the chicken with salt and pepper. Fry in butter or oil on medium heat until the filets are cooked through, and register 165 degrees (75° Celsius) with a meat thermometer. Lower the temperature towards the end to avoid dry chicken filets.
Serve the chicken on a bed of leafy greens and place a generous amount of herb butter on top.
