Miso Mushroom Salad

My husband and I recently returned to Izakaya Minato in Portland, Maine on a weekend vacation to get out of the house and eat a bunch of delicious food. One of the stand out dishes was the Kinoko Salad, consisting of sauteed mushrooms and roasted delicata squash in a rich soy and butter sauce over lightly dressed baby spinach. The sweet squash and gently dressed spinach balanced the bracingly salty sauce perfectly. I knew after we ate that dish I wanted to make a version of it at home.
