You are very lucky to have a source for the real thing. You also have access to game that might be a substitute?
@berdie You no doubt have the same resource - A grocery wholesaler - The place the grocery stores or food vendors buy from... Mine will sell to any business, and since I have business accounts, that is no problem.
I can't get at the name of the stuff I get (I ain't got it here now) but it comes in a wide flat box, maybe 100-150 strips... Pre-cut, looking a whole lot like a bacon strip other than color. Either beef or lamb, and either takes the freezer just fine... Just rebag em into a zippy or some such.. haul out a strip or two, throw em in a hot cast pan for a bit, and you are ready to go...
