Marinated Cucumber, Tomato, and Onion Salad

Marinated Cucumber, Tomato, and Onion Salad is the perfect summer salad. It’s both sweet and tangy and the fresh crispness of the cucumbers and onions can’t be beat.

This summer salad is a simple mixture of oil, vinegar, sugar, salt and pepper along with sliced cucumbers, tomatoes, and onions. I love to serve it really, really cold and will often add ice cubes to it just before serving. So refreshing on a hot summer day!

Cucumbers are so plentiful and inexpensive during the summer months. If you have a vegetable garden, you no doubt have more than you know what to do with. Cucumbers are also amazingly low in calories and have a very high water content. They are a great way to stay hydrated and full during the summer.

Tips for making Marinated Cucumber, Tomato, and Onion Salad:

This is a basic, simple recipe that can be easily customized.

  • Add some chopped fresh dill or some dried Italian seasoning for more flavor.
  • Use red onion instead of sweet onion.
  • Use cherry tomatoes instead of regular tomatoes.
  • Instead of apple cider vinegar, use rice wine vinegar, distilled white vinegar, or red wine vinegar.
  • Olive oil can be used instead of vegetable oil.
  • Peel the cucumbers or leave the skin on.

    I make this all the time. I use 1/4 cup of white vinegar and 1/4cup of red wine vinegar in place of ACV. Love the taste the red wine vinegar adds.
