For a vegetarian option, omit the bacon and add a tablespoon of smoked paprika to the butternut squash before roasting to add a smoky depth. To save time, you can purchase pre-cut butternut squash. Feel free to substitute other nuts for walnuts, such as pecans or almonds. The maple vinaigrette can be made ahead of time and stored in an airtight container in the refrigerator for up to a week. If you don't have apple cider vinegar, white wine vinegar or balsamic vinegar can be used instead. Adding toasted pepitas would work well with the fall theme of the dish.
