Ingredients You’ll Need
Here are the ingredients you need for this cucumber and tomato salad. See the recipe card below for the exact measurements.
- Red Onions are marinated in the vinaigrette, which mellows their flavor.
- Salt and Black Pepper to season the veggies
- Cucumber Tomato Salad Dressing: Red or white wine vinegar and extra virgin olive oil
- Persian Cucumbers are small cucumbers with thin skin and minimal seeds, which makes them less watery than regular cucumbers. Garden cucumbers or English cucumbers can also be used.

How to Make Cucumber Tomato Salad
This easy cucumber tomato salad takes less than 15 minutes to make! While the red onions are marinating, chop the remaining vegetables. See the recipe card at the bottom for printable directions.
- Marinate the Onions in a bowl with the salt, oil, and vinegar.
