A tasty vinaigrette, loaded with a gentle onion flavour backed with just enough sweetness to make this irresistible. Try it over a bed of fresh greens, you won't regret it.
Add all the ingredients, except the oil, into a high-power blender (such as a Vitamix). Blend for about 30 seconds or until the sugar is completely disolved and the onions are minced.
Remove the cover from the lid, and slowly pour in the oil. Blend this for about 3-4 minutes more or until the vinaigrette has thickened.
Store in a mason jar in the refrigerator. Keeps for weeks.
