Bierocks (Cabbage Burgers) This recipe comes from a whole lot of trial and error and I think I finally got it right. I believe your family will love it, while the meat mixture is great, the secret is really in the bread. These Bierocks are great for a quick after school snack, wrap the cooled bierock in a paper towel, and place in freezer bag, freeze. Remove one as needed keep wrapped in paper towel and place in microwave on high for about 1 1/2 minutes and enjoy
