Greek Yogurt Salad Dressing (with fresh herbs)

0 Combine fresh herbs, yogurt, mayonnaise, mustard, lemon juice, honey, and garlic clove in a jar (if using an immersion blender) or the bowl of a food processor or blender. 
1 Blend until smooth. If the mixture is too thick to use as a salad dressing (thickness will vary depending on the type of yogurt used), add water a bit at a time and continue to blend until smooth and pourable. 
2 Taste the dressing and adjust if needed. Depending on the type of herbs you use, you may want to alter the flavors to add some sweetness from more honey or more sour flavor from lemon juice.
3 Can be made up to 4 days ahead. Stir well before serving.
