Make small, shallow cuts in a crisscross pattern on the surface of the kielbasa. This will help it cook faster and absorb more flavor.
Preheat your grill and cook kielbasa for 4-5 minutes on one side, then flip it over and grill for another 4-5 minutes.
Warm up the buffalo sauce and set aside.
Brush on the buffalo sauce and add it to a warmed bun. Garnish with blue cheese crumbles and ranch dressing. Enjoy!
