What ingredients do you need for Cucumber, Onion, and Tomato Salad?

To prepare Cucumber, Onion, and Tomato Salad, gather the following ingredients: tomatoes, cucumbers, onion, vinegar, sugar, salt, cracked pepper, olive oil, and water. Each component contributes to the overall flavor and texture of the dish.

The cucumbers add a refreshing crunch and hydration, making this salad a perfect warm-weather dish. Tomatoes contribute vibrant color, sweetness, and essential vitamins like vitamin C. Onions lend a sharp tang that balances the salad’s flavors; if you prefer milder onions, you could use sweet onions instead, which would soften the sharpness considerably. For those maintaining a low-carb lifestyle, swapping regular sugar with a low-calorie sweetener can keep this dish’s sweetness intact while lightening the carb load.
