Combine all ingredients in a food processor, blender (with a lower blade), or an immersion blender in a tall container, and blend till combined. Stop blending as soon as the dressing has combined and is smooth - just a few seconds. Over-blending can cause the dressing to separate, or the taste to become more bitter.
Taste and adjust any seasonings. Pour into a glass jar and refrigerate till ready to serve.
Notes
Use fresh ingredients - no dried basil or parsley. Garlic powder can be used in a pinch but not recommended.
Too acidic? Add more honey. Not enough? Add more vinegar. Vinegar can also be substituted with lemon juice or red wine vinegar (not HYH).
Dressing will store well for up to a week in the fridge or freeze it into small ice cubes.
