Funny how things work out like this. Yesterday I posted about pre-chopping onions, carrots and celery for soup and today I read about Mirepoix for sale in our Trader Joe's flyer.
Mirepoix is a combination of celery, carrot and onion. The "holy trinity", which is apparently the essential ingredient in dozens traditional French dishes (and all of my soup recipies).
If time is really and issue and you live near a TJ's it sounds like you can buy you mirepoix chopped, mixed and ready to go. I will probably stick to creating mine at home, but at least I know what I am doing.
