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.
Those ingredients you listed are literally the ingredients to a dish called cucumber salad. Though usually the dressing is more of an vinegary Italian dressing instead of ranch. Just Google it.
