I think one of the tricks is to purposefully plan time to cook that's not right before you're planning to eat, so it's an activity/hobby, not a necessity. If I have to cook when I'm hungry, I'll probably just make do instead, but if I say "ok, Saturday afternoon, I'm gonna make a pot of soup, because that'll be delicious later," it's a lot less dreadful, imo.

Ice cubes of chili? Either I eat way to much or you are very much more behaved with portion control and eating several times a day.
I'm pro one meal, eat until full.. fast till I pick a time a time to eat the next day. Then again if I made chili I'd put garlic/onions in the pot bottom first, then meats to brown, then all other ingredients. Cook it all in one pot then when done eating, put the pot in the fridge on a heat mat. Eat the same thing until it's gone.

Which would usually only take a 2-3 days.

Having someone else in the house and having to make other meals makes meals so much harder..

"We had that yesterday" - apparently what many other people say.
