I used to toss all my vegetable scraps in the trash without a second thought...
About six months ago I started keeping a bowl on my counter for onion ends, carrot peels, and celery tops. Back then I'd just scrape everything into the bin after prepping dinner, maybe 3 or 4 pounds a week of scraps gone. Then a buddy from my night shift mentioned he freezes his scraps and makes broth once a month. I tried it out and now I have a gallon bag in my freezer that fills up over two weeks. When it's full I throw it all in a pot with some salt and water, simmer for an hour, and get 2 quarts of broth for free. It saves me around $4 every time and keeps that stuff out of the landfill. Has anyone else found a simple swap like this that actually sticks?
