In a large resealable freezer bag, combine chicken thighs, lemon zest, lemon juice, Dijon mustard, honey, olive oil, salt and the choose-your-own adventure seasoning of your choice (Herbs or Harissa). Mix well to coat chicken evenly.
Pressing out air, seal bag; freeze. The chicken will keep for 1 month frozen.
When ready to grill, thaw chicken. If you’re camping, the frozen chicken will keep for two days.
Arrange a grill over medium-hot charcoal with direct and indirect cooking zones.
Place chicken skin side down on grill and cook until browned, flipping and moving around as necessary to avoid charring or flare-ups, about 10 minutes. Move thighs to indirect heat and cook until juices run clear when chicken is pierced and thermometer inserted into thickest part reads 165°F, about 10 to 20 minutes more.
