Bulgarian kebabche is like a raw sausage without casing, typically made of equal amounts of ground beef and pork. The most common spices used in kebabche are cumin, S&P. Sometimes finely chopped parsley could be added to the mix.
Unlike the Bulgarian "kufte" (meat patties, shaped like smaller but thicker hamburgers), kebabche doesn't have any onions. Also, unlike the Middle Eastern or Turkish kebabs, kebabche is not skewered when grilled.
Balkan Flavor usually carries frozen kebabcheta (plural for kebabche) that are quite tasty and pretty close to the ones you'll find in Bulgaria.
