NO, I never do batch cooking. The freezer in our side by side fridge is used motly for ice and iced cream and frozen pizza (both DH and DS will add some toppings and eat one of those if home alone). If plans time after I have bought groceries, I might pop a package of meat in there to thaw later for use, but that's about it.
Food just tastes so muc better fresh, IMO, and honestly any of the three adults in our house can pull together at least a dzen meals in 20ish minutes on a busy night-----I don'T think thawing and reheating a batch made item would be much faster (maybe less so, wouldn't you have to be home and plan ahead and take it out of the freezer to thaw several hours in advance?)
We eat out most holidays (generally travel for Christmas).
I make a small turkey breast every 2-3 weeks in winter months. It'S DS's favourite and he never leaves any meat. If he did, yes, I would out uneaten meat in the fridge and use it in pot pies or something in the next day or 2, but it never happens. In any event, I would not consider a plain meat as "leftover" more as a base ingredient in something new. Just like we might use some of a package of carrots when making roasted vegetables on Monday and then a couple more in dumplings on wednesday and maybe have carrot sticks to munch on Friday. I would not consider myself to be eating leftover carrots on wednesday and Friday----maybe you would? Perhaps this is more a semantics issues and we do not define leftovers the same?
