Go through all your cupboards and pull out anything old & nasty, which goes in the trash, and anything you just aren't going to eat in the next 30 days. That stuff should go in a bag and you should take it TODAY to your local food bank.
If you can make time for it, pull everything out, wipe down the cupboard & dust the cobwebs out, and then put back the keepers.
Update the shopping list with those staples you would eat in the next 30 days if only you had enough of them.
