Slow cooker stuff if I’m lazy but thinking ahead a bit. Just throw shit in a pot and turn it on. I tend to get big lumps of meat rather than steaks or whatever, so the slow cooker has the added benefit of me not needing to do much cutting. I just do a few big chunks and it’ll be so tender by the time it’s ready it’ll fall apart. Takes longer to put it away in containers than to prep it, then I’m done cooking for a week lol

Spaghetti bolognese is a regular if I need something soon. Little more work, but it’s extremely quick and doesn’t require being in the kitchen for the whole thing. Still makes a ton of meals that keep and reheat nicely.

Roasts are nice if I’m sort of having to impress someone but I’m lazy. You just throw shit in the oven and wait. Occasionally come back to throw in something that has a shorter cook time than the meat. Might be heresy but I’ve never really been keen on the leftovers of a roast though, so one cook is usually only one meal and maybe a sandwich the next day instead of several.
