Hello? Do all you people think that everyone, who is low-carbing, is as affluent as you are? Some of us live on limited budgets, in small apartments, with small apartment sized fridges, with even smaller freezer compartments. We can't buy in bulk, cook in bulk, freeze in bulk, and can in bulk. On the brighter side, we end up taking the bus to the supermarket more often, eating fresher (because we can't store anything) and getting our exercise by lugging those bags of fresh items from the bus stop to our apartment building and up three flights of stairs.
Sorry, needed to get that off my chest. As for canned beef, don't have an opinion yet. How heavy is the can?
