Franz has been the staple hot dog bun for over 100 years, so you can trust Franz to deliver the taste your friends and family will love. They are the perfect size for hotdogs, veggie dogs, and brats hot off the grill. A tip for toasting the buns: Once the grilled meat is done, brush the inside the buns with some olive oil and place them directly on the grill grates for about 30 seconds.
