In a medium bowl, whisk together the gochujang, vinegar, sesame oil, soy sauce, garlic, ginger, green onions and brown sugar until smooth.
Slowly drizzle in the olive oil while whisking constantly to emulsify.
Taste and adjust seasoning as desired.
Serve immediately or refrigerate in an airtight container for up to 2 weeks. Whisk dressing before serving to re-emulsify.
Drizzle over salads, grains, grilled meats, roasted vegetables, or wherever you need a flavor boost!
