Which three ingredients are found in the Greek salad?

The combination of feta, tomato, and cucumber is characteristic of a traditional Greek salad. Feta cheese adds a tangy and creamy texture that is a staple in Greek cuisine, providing a rich flavor that complements the freshness of the vegetables. Tomatoes lend juiciness and sweetness, typical of Mediterranean salads, and cucumbers introduce a refreshing crunch that balances the other ingredients.

When considering the other combinations, while some may include common salad elements, they do not embody the classic flavors and ingredients associated with a Greek salad. Pepper, onion, and cucumber, though viable salad ingredients, miss the signature element of feta. Similarly, basil, olive oil, and bell pepper do not align with the traditional components of a Greek salad, as they focus on other flavors that are not central to this particular dish. Lastly, lettuce, carrots, and olives make a diverse mix but stray from the expected core ingredients of a Greek salad, which emphasize the tomatoes and feta.
