You can use peeled and diced butternut squash instead of sweet potatoes.
For more mild cheese, use feta or goat instead of blue cheese.
To make the salad vegan, omit the cheese or substitute with a plant-based version. Also, use maple syrup in the vinaigrette instead of honey.
Keep leftovers in an airtight container in the refrigerator up to 3 days. If you are planning to save part of the salad to eat at another time, do not toss it in the vinaigrette and store the dressing in a separate container from the salad. You will need to let the vinaigrette sit out at room temperature for 15 minutes before you toss it into the salad, because the oil will harden in the cold temperature of the fridge.
