Think about which items you use now in your kitchen daily for preparing meals. I use the food chopper WAY less than I thought I would.
I DO use the 2 mixing bowls w/lids almost daily.
Their spatulas are also wonderful. Those I use daily as well.
I also have a few of the stones. I use them for making bacon in the oven, making biscuits, brownies, etc.
I have also been very happy with their knives. I use those almost daily as well.
See if the PChef rep is having any sort of special this month that you can get in on.
