When was greek salad invented?

It's impossible to say definitively when Greek salad was "invented". There's no single historical record of its creation. However, we can piece together its origins:

* Ancient Greece: While not exactly the modern Greek salad, ancient Greeks definitely ate a combination of tomatoes, cucumbers, olives, and feta cheese. These ingredients were part of their daily diet.

* 19th Century: The tomato, originally from the Americas, didn't reach Europe until the 16th century. It wasn't widely consumed in Greece until the 19th century, coinciding with the rise of the modern Greek salad.

* 20th Century: The salad as we know it likely evolved in the early 20th century, particularly in the 1920s, with the addition of red onion, oregano, and the popular vinaigrette dressing.

So, rather than a singular "invention," the Greek salad emerged over time as a combination of traditional Greek ingredients, influenced by the introduction of the tomato and changing culinary trends.
