To prep ahead for Thanksgiving or a holiday party:
- Measure the cranberries and nuts ahead and store at room temperature.
- Make the dressing up to 1 week ahead. Store in a jar in the fridge. Shake or whisk before using.
- Slice the shallot up to 2 days ahead. Store in an airtight container in the fridge.
- Chop the cheddar up to 2 days ahead. Store in an airtight container in the fridge.
- Slice the apple the morning of at the earliest. Toss with a squeeze of lemon juice to slow browning, then store covered in the fridge.
- At serving time, add the greens to a large bowl, layer all toppings over, drizzle with dressing, and toss.
