To become a salad
A salad is not (as I grew up believing) cucumbers, tomato and lettuce in a bowl.
Those are components that could make up a salad. To become a salad the components need to be transformed.
A salad is dressed by tossing it. Mixing the components with a dressing that balances the whole experience.
Best done with the components clean and dry. In this way, the parts come together as a whole.
