I get very cranky when I waste food. And it seems like I’ve always got a broccoli stalk or some vegetable that I either won’t use, or can’t get to before it will go bad. So my new thing is to keep a bag in the freezer, where I toss all vegetables that can be used in a stock. When the bag gets full, I make a stock, saving myself the cost of buying the stock, and the waste on the food. It’s pretty win-win.
