Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Chicken breasts: Provides the main protein and bulk of the salad.
Mayonnaise: Binds the salad and adds richness and moisture.
Lemon juice: Adds acidity that brightens flavor and slows browning of cut avocado.
Avocados: Add creamy texture and richness to the salad and serve as the shells.
Celery: Adds crisp texture that contrasts with the soft chicken and avocado.
Red bell peppers: Add crunch and mild sweetness.

The step that matters

Drizzle the avocado half-shells with lemon juice. Cut avocado flesh oxidises and browns quickly when exposed to air. Acid from lemon juice slows this browning, so the shells should be coated before filling and the diced avocado should be added only just before serving.
