My significant other ate cucumbers and onion with some ranch. I called it a cucumber onion salad. She says there aren’t enough ingredients to call it a salad, because “it takes multiple ingredients”. I pointed out she had three and asked what the minimum is. She refuses to answer so I ask Lemmy.
So by your definition at least two ingredients are required for a salad.
Yes. Dry lettuce in a bowl is not salad.

Dry lettuce in a bowl is a honeymoon salad. Lettuce alone, undressed.
