Mirepoix

Carrots, celery, and onion were on sale so I loaded up. Knowing I wasn't going to be able to use it up in a timely manner, I decided to make a mirepoix and freeze it in 1/2 cup quantities. I spent I don't know how long chopping; I just can't bring myself to use a food processor. I ended up with three cups of carrots, three cups of celery, and six cups of onion. That's a lot of chopping. Here's the result.
