History

The Romans and ancient Greeks ate mixed greens with dressing, a type of mixed salad. Salads, including layered and dressed salads, have been popular in Europe since the Greek and Roman imperial expansions. In his 1699 book, Acetaria: A Discourse on Sallets, John Evelyn attempted with little success to encourage his fellow Britons to eat fresh salad greens. Mary, Queen of Scots, ate boiled celery root over greens covered with creamy mustard dressing, truffles, chervil, and slices of hard-boiled eggs.

Oil used on salads can be found in the 17th-century colony of New Netherland (later called New York, New Jersey and Delaware). A list of common items arriving on ships and their designated prices when appraising cargo included "a can of salad oil at 1.10 florins" and "an anker of wine vinegar at 16 florins". In a 1665 letter to the Director of New Netherland from the Island of Curaçao there is a request to send greens: "I request most amicably that your honors be pleased to send me seed of every sort, such as cabbage, carrots, lettuce, parsley, etc. for none can be acquired here and I know that your honor has plenty,...".

Salads may be sold in supermarkets, at restaurants and at fast food chains. In the United States, restaurants may have a salad bar with salad-making ingredients, which the customers will use to put together their salad. Salad restaurants were earning more than $300 million in 2014. At-home salad consumption in the 2010s was rising but moving away from fresh-chopped lettuce and toward bagged greens and salad kits, with bag sales expected to reach $7 billion per year.
