Hoisin mixed with rice vinegar and sesame oil makes a salty-sweet-tangy-nutty dressing for tender chunks of roasted butternut squash. You can purchase already peeled and cut squash from the grocery store, but keep in mind that if the pieces are smaller or larger than specified here, you may need to adjust the cooking time. Use a broiler-safe rimmed baking sheet, as the squash chars for about 10 minutes under the broiler.
