For the dressing, in a small jar with an airtight lid, combine all ingredients for the vinaigrette using the minimum amount of maple syrup and a generous pinch of salt and pepper. Shake vigorously to combine. Taste for sweetness and seasoning and adjust accordingly with additional maple syrup, salt, and pepper. Shake again to combine.
For the salad, in a large bowl combine greens, squash, apple, and protein of choice. Add desired amount of dressing and toss to combine. Season with salt and pepper. Add in half of the nuts and goat cheese. Toss very gently just to mix. To serve, portion salad into two large bowls and top with remaining nuts and goat cheese.
Vinaigrette can be made in advance and will keep for up to a week in the fridge. For meal prepping, store ingredients separately and combine before eating.
