Like a big pot of soup, some fried meat and whatever side dish like cooked cabbage. The idea is to spend the unpleasant cooking time once, put it all in the fridge then for a few days at least the whole effort is just to retrieve servings and heat them before eating.
Most of the times I finish what I cooked before starting to spoil but even spoiling isn't very sudden. Like I ate 5 days old soup yesterday and tasted a little funny but it was all good, no side effects. There's still a bowl left at the bottom of the pot today and by the time I'm hungry it's too late to start thinking and waiting for alternatives so what the heck. What doesn't kill you makes you stronger I guess. Therefore it happens sometimes that I wakeup at 2 AM with an acute feeling that a bowel evacuation is imminent if you know what I mean :)
