For meals, how about something like freezer crock pot meals? (this is the first example from Google--there are many others)
Piggybacking off of what Jean said, could the kids earn a token for each chore done? My kids are younger than yours, so take that into consideration :) Mine earn a bean (just a dry pinto bean) when they do a chore, which is then worth x amount of screen time or, at the end of the week, y amount of money. I could definitely understand if you don't want to use money, but could you come up with some sort of currency that works for each kid?
Could you get a load of laundry started in the morning, and have one of them switch it to the dryer, so the only thing left to do is fold? (Each of mine, yes, even the 3yo, folds and puts away their own laundry.)
I hope you can find some way to make this manageable for you. :grouphug: again.
