If making the *Butter Lemon Chicken,* combine all of those ingredients in a saucepan and heat until the butter melts. Pour over the chicken and marinate all day or overnight for best flavor. (I like to use a zipper-top bag, but a covered bowl may be used instead.)
If making the *Lemon Herb Chicken,* combine those ingredients in a zip-top bag or large bowl. Add the chicken and marinate all day or overnight for best flavor.
When ready to eat, prepare the grill. Allow the chicken to sit at room temperature until the grill is ready.
Remove the chicken from the marinade, discarding the remaining marinade, and grill over medium heat for 7-8 minutes per side, depending on thickness, or until the chicken is just cooked through. Remove from the heat and allow the chicken to rest for 5 minutes before eating.
