Skip processed mystery meat dogs and try Let’s Be Frank’s hot dogs made from 100 percent local and 100 percent grass-fed beef or sausages made from pigs humanely raised on family farms. All food is free of nitrites, artificial flavors, colors, fillers and preservatives and animals are raised without antibiotics or hormones. Buns are locally made using organic flour, and even the condiments are organic.
