Peel the skin back from each chicken leg, exposing the flesh and leaving the skin attached to the base of the chicken leg. Using a pairing knife, loosen the meat around the bone and scrape the meat back, exposing the bone. Using the heel of a chef's life, carefully cut bone at the end where the skin and heart have been pulled back, leaving the bone's end intact. Reserve for stuffing
Pork filling
In a large skillet heated to medium-high heat, add the olive oil and brown the ground pork, breaking apart with a whisk. Add the dry ingredients and cook out (about 4 minutes). Add the bbq sauce and remove from heat. Allow to cool in the fridge for stuffing.
Hot-BBQ sauce
Add all ingredients in a small sauce pot, mix well, and allow to simmer (about 2- 3 minutes) slowly. Reserve for pork filling and final saucing.
Buttermilk onion dip
In a small mixing bowl, combine all ingredients. Reserve cold for plating.
Assemble, Cook and Serve
Stuff the chicken legs with the cooled pork filling, pulling the meat back up around the filling. Lastly, remove the chicken skin over the beef and re-shape it into the chicken leg shape. Sear the chicken legs on all sides in a hot skillet with olive oil. Place in the oven until the chicken meat is fully cooked and the beef & filling reach 160 degrees F. Remove from oven. Add the chicken legs to a mixing bowl and gently toss with the hot BBQ sauce. Plate beside the buttermilk onion dip and enjoy.
