There are times when my celery and carrots start to languish in the veggie drawer.  At this point in time I chop up the celery and slice up the carrots and put them into the dehydrator. When they are all dried up I put them into the food processor to grind up into bits and pieces.  Into a jar they go with dehydrated tomato skins and some dehydrated leeks where it will get added into soup broth when the time comes.  I have to thank Pinterest for the idea and this food post.

Another favorite thing I like to make and use for soups is this yummy food post.
