Chinese mustard has a bit of kick, so if spice isn't your thing, use Dijon instead. Try this healthy salad dressing over your favorite greens or as a marinade for shrimp.
Combine grapeseed oil, vinegar, chives, mustard, sesame oil and salt in an 8-ounce mason jar. Shake vigorously until combined.
To make ahead: Refrigerate for up to 1 week; shake before serving.
