DO-AHEAD TIP: Marinate chicken overnight or for at least 4 hours (see recipe)
Prepare marinade: Place the first 7 ingredients in a food processor or blender (garlic through thyme); process until smooth.
Place chicken in a large zipper-topped plastic bag and pour marinade on top.
Seal bag and turn to coat; refrigerate overnight or for at least 4 hours, turning occasionally. At the time of cooking, melt the coconut oil in a large skillet over medium-high heat.
Remove chicken from marinade (discarding marinade and bag) and cook for 4 to 6 minutes per side or until cooked through.
