Fresh herbs are a welcome addition to any salad dressing. For a simple vinaigrette, blend a handful of chopped herbs with olive oil, vinegar or lemon juice and a little mustard. Taste and adjust as you like - add more vinegar or lemon juice if too rich, add more oil if too sour, add more herbs, mustard or seasoning for a stronger flavour. This summer nectarine and ham salad has a lovely fresh basil dressing you could try. If you like things creamy, stir your favourite herb through ready-made mayonnaise, or make the ranch-style dressing from this meaty steak and potato salad.
