Bulgar pilafs are popular throughout the Middle East, and this version, featuring hearty winter squash, combines the nuttiness of bulgur with the earthy sweetness of butternut squash. The grain and squash cook in about the same amount of time, so the dish comes together quickly in a single pot. A squeeze of lemon juice contrasts nicely with the sweet squash and raisins. If you like, garnish the pilaf with a handful of chopped mint to lend color and freshness. Be sure to use coarse bulgur, rather than finely ground; the hearty texture of coarse bulgur holds up well when cooked for a pilaf.
