In a large bowl, combine all ingredients for the chicken. Use your hands to toss everything around until chicken is well coated in marinade. Cover with plastic wrap and refrigerate at least 20 minutes (up to 1 hour).
Preheat the oven to 400 degrees F.
Transfer chicken (including marinade) to a foil-lined baking sheet or a casserole dish. Bake 30 to 35 minutes, until chicken is cooked through. Increase oven heat to 425 degrees F and bake an additional 8 to 10 minutes, until skin is golden-brown and crispy.
Remove chicken from oven and allow it to sit 10 minutes before slicing and serving with magic tahini sauce.
Add all ingredients for the sauce to a small blender and blend until smooth. Taste sauce for flavor and add lemon juice or sea salt to desired taste.
