Most people make relish out of cucumbers, but my Grandma was always known for her zucchini relish. 

Since Grandma passed this recipe down to me, I have absolutely fallen in love with it. It requires very few ingredients to prepare and the taste is outstanding!

Plus, it is another recipe to use the abundance of zucchini that comes out of the garden each summer besides making loaf after loaf of Zucchini Bread.

We use zucchini relish as a condiment for hot dogs and hamburgers. However we also use it to brighten up our deviled eggs, egg salad and even in our ham salad recipes.  

It is a great staple to have in the pantry or to share with friends.  Best of all, you know that you made it yourself!
