This zucchini and green tomato relish recipe is the perfect way to use up the abundance of these vegetables that might be lingering in your garden. The relish is made with zucchini and green tomatoes (of course!) along with bell peppers, onions, pickling salt and spices, garlic and other spices, then canned in clean, glass jars. 

Get ready to make this recipe by prepping the zucchini, tomatoes, peppers, and onions and chopping them. We used the coarse grind of a stand mixer's grinder attachment to make this sweet relish. You can finely chop the vegetables if you don't have a grinder. Plan accordingly as the gound veggies need to sit in the pickling salt for three hours before mixing with the other ingredients and canning.

This is a great relish for hot dogs or burgers, or can be used as a condiment on sandwiches and salads, as a topping for potatoes, or on entrees. You can also use it to make tartar sauce. It's good with cheese too!

"This relish was delicious. I’ve been using it in all my sandwiches and burgers since making it. It’s sweet, tangy and packed with flavor. I’ve also been mixing it with mayo which is absolutely delicious as a condiment. Luckily, it makes plenty, so enough to share with friends and family!" —Cara Cormack
