I find I can change people's minds rather quickly. As fast as I can boil a pot of water. Celery, peppers and onions (Cajun mirepoix.) Or celery, carrots and onions (mirepoix.) Add salt and they have a taste. The first woman I did that to, made chicken soup out of it. She pulled vegetables first and added them back in at the end. She said it tasted so good she couldn't let it go to waste. Made a good cook out of her.
