Lunch. I am divorced, kids live with mom and they don't come here often. Usually I go out there as mom has the house (we are friends.)
When I cook, I cook a lot. I buy 2 packages of pork chops and cook all 10-12. Make a big pot of mashed potatoes, veggie, mushrooms, and I have 12 containers in the freezer. 3 lb. of spaghetti at a time. Tacos, 2 lb. of meat and seasoning. I get dinner and 5-6 bowls of soup or chili from the Instant Pot. All goes in the freezer. Hot sausage for a sausage sandwich, cook 2 packages at a time.
Take one out and I head to work. Leave it on my desk and it's usually nearly thawed by lunch time except for soups/chili. Those seem to stay frozen completely.
Walmart Italian sandwich buns freeze extremely well and thaw fantastic. If I get some lunch meat, bun comes out of the freezer and I wrap it in a paper towel and leave on my desk. Lunch time and the outside is nice and crusty and still deliciously soft on the inside. I actually like them better doing this than when they are fresh as the outside gets crusty.
Note, I work in manufacturing and quite a while ago I thought, why bother coming home exhausted from labor all day in extreme heat (going to Disney was great because at 107° I got a big relief from the heat I'm normally in) and spending the rest of the day cooking and cleaning. I'll eat dinner at lunch time when I'm working and hungry, then have something simple when I get home. I generally cook one thing on a weekend and have 1 to 1.5 weeks worth of meals which after the initial gotta cook more for variety, I'm rotating my lunch meals pretty good in the freezer. Currently there's pork chops (my chicken since I don't like chicken), steak for fajitas, spaghetti, stuffed pepper soup, sloppy joe, and BBQ pork from the crock pot all individual meals ready to pull out at 6 am.
I have a small fridge/freezer and I haven't grocery shopped I think since just after Thanksgiving. I have enough food cooked and frozen in meals that I probably could go 3 weeks without cooking.
