Soak the pitted dates in warm water for about 10-15 minutes to soften them.
Drain the water and transfer the dates to a blender or food processor.
Add the lime juice, water, maple syrup or agave nectar (if using), vanilla extract, and a pinch of salt to the blender or food processor.
If desired, add the optional olive oil or any other preferred oil to the blender or food processor.
Blend all the ingredients together until smooth and creamy. If the dressing is too thick, you can add more water, a tablespoon at a time, until you reach your desired consistency.
Taste the dressing and adjust the sweetness or tanginess by adding more maple syrup/agave nectar or lime juice if desired.
Transfer the dressing to a jar or container with a tight-fitting lid.
Store the dressing in the refrigerator for at least 30 minutes to allow the flavors to meld together
Give the dressing a good shake before using it. Drizzle it over salads, roasted vegetables, grain bowls, or any other dish you like!
