Chef Jonny Schwass serves this side dish at room temperature, but you can also warm the squash before it gets a final dressing of nuts and cheese.

Heat the oven to 375°F. Place the squash whole on a baking sheet, and bake for 40 to 45 minutes, or until a fork slides in and out of the squash easily. Set aside until cool enough to handle.

Discard the skin and seeds of the squash, and cut into bite-size pieces. Place the squash in a bowl. Drizzle with about half the vinegar and olive oil, and season generously with salt. Toss gently to incorporate all the ingredients. Arrange the dressed squash on a serving dish, and top with the remaining vinegar and oil and the pistachios and pecorino. (Alternately, the squash can be cut in half, as pictured, and topped with remaining ingredients.)
