What each ingredient does

Lettuce: Forms a crisp, cool base that gives the salad its fresh texture.
Bananas: Add natural sweetness and a soft, creamy texture.
Oranges: Add acidity and juiciness that brighten the sweeter fruit.
Mayonnaise: Adds fat and richness, coating the fruit and binding it into a creamy dressing.
English walnuts: Add crunch and a toasty, fatty flavour that contrasts with the soft fruit.
