Combine all ingredients in a small mason jar, close the lid tightly, and shake vigorously. Serve immediately.
You can also use an immersion blender for easier mixing.
Notes
Store in the refrigerator for up to 1 week. If refrigerated, the dressing may solidify slightly. This is perfectly okay. It happens when olive oil is chilled. Simply remove from the refrigerator and let it come to room temperature about an hour before you need to use it
