Special Thanks to Krishnan, one of our great friend, who introduced us to this dish and gave us the recipe. Olan is an essential dish in the traditional Kerala Onam Sadya. We love Olan with theeyal and rice. As olan by itself is mild, it goes well with something spicy/tangy. Authentically Olan is made with white pumpkin and black eyed peas or cow peas, but using yellow squash is a variation....
