Begin prepping your chicken drumsticks. Using a really sharp knife, slice one area on the drumstick from top to bottom all the way down to the bone.
Pull apart the two sides of the slice and begin separating the meat from the bone so that the chicken drumstick is flayed open and flat. Make sure to leave some part of the meat, on the opposite side of the first cut, still connected. Repeat this for all of your drumsticks.
In a food processor, add all the ingredients for the marinade and blend until smooth.
Add all of your chicken drumsticks to a food safe bowl or bag and pour the marinade over top (make sure to save 2-3oz of marinade for basting later). Mix together thoroughly, cover and place in the fridge to marinate for at least 4 hours but ideally overnight.
The following day, preheat a medium-high heat fire (around 350-375 degrees F) for direct cooking.
In a food processor, add all the ingredients for the Green Sauce and blend until smooth. Set aside until ready to use.
Pull your drumsticks out of the marinade and discard any excess marinade.
Place them onto the fire and cook them for 20-25 minutes until they reach 170F internal. Make sure to flip them every 3-4 minutes to prevent burning, and move the chicken around in case you have a hotter spot on your grill.
Right before they are done, baste the outside of the meat with the reserve marinade. Once done, pull them off and let them rest for 5-6 minutes.
Drizzle the green sauce over the top of the drumsticks or serve on the side. Enjoy!
