I was recently in Pittsburgh visiting friends and got to try a delicious steak and cheese sandwich on my first trip to Primanti Brothers. I have hated cole slaw all my life, but the cole slaw on that sandwich was delicious. Does anyone out there have a recipe or know a secret for making it that good? It was vinegar-based, not mayo, for those who haven’t been there. I know I could never live up to the original, but I’d like to try and make a BGE version of this sandwich.
