Discovered by accident a few summers ago.. Was cooking pork steaks outside on the charcoal grill. Realized I had not thought about a vegetable. (other than a sweet potato roasting in foil alongside the meat). Anyway, Checked out the freezer in desperation. Grabbed a bag of frozen brussels. Threaded them on a skewer, brushed with melted butter and threw them on the grill. When I closed the lid on the grill to finish everything up, the charcoal smoke taste really kicked those BBs up a notch! Delicious!
