Maui Onion Avocado Toast


Maui is a beautiful place and so is the plethora of food available. With many cultural influences and a creation of dishes to call their own. The Maui onion is one such vegetable that gains its characteristics strictly from the soil located on the island itself. The Maui onion is grown in the volcanic soil on Mt. Haleakala. This gives it the sweet, succulent, mild, and tender aspects that it’s known for.

I pickled the onions for this recipe. You can pickle them for one hour or overnight for best results. Of course if you do not have a Maui onion on hand, you’re welcome to use any type and you can also serve it in its raw form as well.
