The heart is cleaned and in large chunks - about an inch diameter and two to three inches long. Sitting in the marinade right now - the marinade is about four tbsp. Dijon, four cloves of pressed garlic, about 1/4 cup EVOO, one tbsp. cider vinegar, one tsp of salt and one tsp of fresh ground black pepper, whisked together. The kabobs will have Vidalia onion and poblano peppers along with the heart. Will do them on the egg as hot as I can get it. Won't take long to cook, maybe five or six minutes.
