Step 1

In a bowl or jar, whisk or shake together the orange juice, orange zest, vinegar, oil, and mustard until combined. Add the shallots, rosemary, and salt. Set aside while you prepare the salad.

Step 2

Using a sharp knife, cut off the top and bottom ends of the orange. Lay the orange on a flat surface so it doesn't tip over. Cut all around the orange, removing the entire peel and white pith, while sparing as much flesh as possible. Cut into 1/2-inch thick slices.

Step 3

Add the spinach to a large bowl or platter. Pour half of the dressing over the spinach. Toss well to coat.

Step 4

Arrange the orange slices and persimmons throughout. Sprinkle with shallots, rosemary leaves and walnuts.

Step 5

Drizzle with some more dressing and season with some salt and freshly ground black pepper. Sprinkle with some feta if desired.
