What each ingredient does

Eggs: Form the main body of the salad and provide its protein-rich, firm texture.
Chives: Add a mild onion-like aroma and fresh flavour to the dressing.
Parsley: Adds fresh, herbal aroma and a bright green note to the dressing.
Plain french dressing: Adds moisture and acidity that coat the eggs and lettuce.
