I buy food in rolls like this for Google for training treats or to give him as an entire meal if he's been especially good.
I buy the roll, then slice the entire thing in quarter-inch thick slices; I then put them in freezer bags and put whatever won't be consumed within a couple of days in the freezer. Slicing it thin like I do ensures that it thaws out quickly. I take out a new bag the day before I need it, to thaw in the fridge. It works out pretty well that way.
