Spinach Salad with Ginger-Soy Dressing

Make Ahead Tip: Cover and refrigerate the dressing (Step 1) for up to 5 days.

Note: Baby spinach is immature or young spinach--it's harvested earlier than large-leaved mature spinach. We like the sturdy texture of mature spinach in cooked dishes and serve tender, mild-flavored baby spinach raw or lightly wilted. Baby and mature spinach can be used interchangeably in these recipes (yields may vary slightly); be sure to remove the tough stems from mature spinach before using.
