This recipe is dead simple. Simply mix the meat together and leave to rest while you sauté the onions in butter at medium heat until they are translucent. Then add the meat in batches small enough that it browns together and doesn't end up boiling in its juices. Cook on as high a heat as possible to maximise the tasty Maillard reaction. Once it's all cooked, add Butt Rub to taste and enough BBQ sauce to coat the meat. Then simply spoon the delicious meat into the bread and serve. Sloppy Joes are even tastier the next day!
