My local Kroger store carries these foot long sub rolls, par baked and ready for a 400 degree oven. I buy several when I see them and pop them into the freezer. They are better when they are baked right away but they don’t lose too much in the freezer if they are thawed and baked before much time has passed. A month is too long. I pulled this one this morning and made a nice sammich. This one has three kinds of cold cuts: Lebanon bologna, ham, and salami with cheddar and havarti. I love slaw on these, this is made with cabbage, onions, and sweet peppers in a seasoned rice vinegar.
