Niman Ranch Grass-Fed Angus Uncured Beef Franks starts with 100% grass-fed Angus beef for a frank with a rich beef flavor and a savory bite. Because it is fully cooked, it is easy to heat while still bringing real sausage flavor to the meal. Like all Niman Ranch beef, it comes from cattle raised by independent U.S. family ranchers with no antibiotics or added hormones, and the grass-fed beef is 100% grass-fed and grass-finished. Heat them on the grill, in a skillet, or on a sheet pan, then build classic hot dogs, chili dogs, or quick family dinners. As an uncured item, it is made with no nitrates or nitrites added except those naturally occurring in cultured celery powder.
