Fill a large stockpot halfway with water and bring to a boil.
Preheat your oven to 350 degrees F.
In a saucepan, cook the white rice according to package instructions. Place cooked rice into a large mixing bowl and set aside.
Working in batches of two or three at a time, blanch the collard leaves for 1 minute in the boiling water. Then, lay them flat on a clean countertop to cool. Hold the leaves by the stem as you blanch them to avoid tearing them with tongs.
In a large saute pan, brown the sausage until the fat renders. Add in the onions, bell pepper, celery, hearts, and livers and cook until the vegetables are translucent.
Add the cajun seasoning, Worcestershire sauce, and cooked rice to the pan. Stir until well combined and return the mixture to the mixing bowl. Set aside on the counter to cool.
Remove the stems from the collard leaves by making cuts on either side of the stem from top to bottom.
Place a spoonful of mixture (don’t overstuff!) into the top ⅓ of a collard leaf. Roll the leaf over once, fold the sides in, and finish tightly rolling the leaf from top to bottom. Place the finished dolma in a 9x13 baking dish and continue until all the collard leaves have been rolled.
Pour one cup of NC-style vinegar barbecue sauce over the dolmas, cover the baking dish with foil, and place into the oven for 30 minutes. The sauce needs to be a thin, vinegar-based sauce. If these aren't available, substitute a 60/40 mixture of chicken stock and apple cider vinegar.
Serve with pepper jelly or another thick, sweet sauce for dipping.
