Does anyone have the recipe for the pickled eggplant side dish found in Boston's North End restaurants?

I have had this at many of the restaurants but don't know how it is made. It's shredded and ';pickled';, but it is still green/white, so I think it is served once it's made and not jarred and aged. It is tangy and has crushed red pepper. I may try mixing a little vinegar, olive oil and salt with shredded eggplant and see what happens!Does anyone have the recipe for the pickled eggplant side dish found in Boston's North End restaurants?
Did you try doing an online search for it?? Maybe just typing in Pickled Eggplant found in Boston's North End restaurants would be a starter point. Good luck.
