You'd think we'd get sick of turkey soup, turkey sandwiches, etc., but we never do.
I applaud your enterprise! I suppose a single person could do that with a chicken.
"Just about every Sunday (except in summer when we grill outdoors),..."
You can still do this in the summer. Go to Sam's, buy a bunch of brats, ribs, steaks, hamburger, etc., Load up the grill with charcoal and spend a couple hours grilling everything. Put it into freezer bags. Mix it up a bit, a meal of ribs, a steak or two, some brats, and a few hamburgers in a gallon bag. Put a couple in the fridge and the rest in the freezer. When you empty one of the fridge bags, take one out of the freezer. Works fine for us. I even grill a couple of weekends a month during the winter.
Turkey is cheap and practical. We used to do the same thing, at least every second week.
As far as this article goes, We just buy bulk meats like chicken breats, the whole pork loin (cut), 40 lbs of hamburgers, and whatever is on sale bulk, and freeze it.
There are different ways of cooking things so I couldn't imagine cooking it all at once and having the same thing over and over again.
Then of course there is our hunting efforts which get cut up and frozen, so with ducks, geese, deer, elk and moose there is no shortage of meat around here, just a shortage of freezer space. Three freezers are just not enough sometimes.
