    ‘Tis the season! Salad season, that is. Ring in the summer with marvelous fresh fruits and vegetables. For me, cucumbers and tomatoes are tops. Salads are needed for this in-season produce!!!

    This salad takes inspiration from two others on this site. One is my Greek Cucumber Salad, with its main ingredients of cucumbers, tomatoes, and red onion. And the balsamic vinaigrette dressing is reminiscent of a Caprese salad. Taking these favorite tastes and making a new salad is an easy button for sure. That’s what summer is all about!

    Easy Cucumber Tomato Salad Ingredients

    It’s a pretty simple ingredient list, and experimenting with different combinations, etc. is easy,  as I describe below.

    • Cucumber (English)
    • Grape Tomatoes
    • Red onion
    • Avocado

    Easy Dressing for Cucumber and Tomato Salad

    You honestly only need 2 ingredients to make this dressing, plus salt and pepper. Whisk them together and toss with your salad!

    • Balsamic vinegar
    • Olive oil
    • Salt + pepper

    How to Make Cucumber Tomato Salad

    I like to mix this salad before I start the rest of the meal, waiting only to add the avocado at the end. It does great just hangin’ out in the fridge for a few hours.

    Start by cutting the cucumber into chunks, halving the grape tomatoes and slicing the onion. Whisk the vinegar and oil together and season with salt and pepper.

    Cucumber Onion and Tomato Salad Recipe Variations

    • Cucumber: I love English cucumbers because of their thin skin. It means I don’t have to peel!! But feel free to use other cucumber varieties if you prefer.
    • Tomato: I always default to grape tomatoes because they have a little extra sweetness in every bite. But cherry tomatoes are a great substitute. You could even chunk up a Roma or a slicing tomato. They are the best when in season!
    • Red onion: In the world of onions, the red variety is described as “sweet.” That always feels wrong to me when describing an onion. You can substitute with a white or yellow onion if desired. Just be aware that other onions can impart an extremely strong taste and could potentially overwhelm the other flavors in this salad.
    • Avocado: I love the creamy texture the avocado adds to this salad. In addition to providing healthy fats, the avocado helps give a feeling of satiety, or fullness, from eating this salad. However, if you prefer to use cheese, some fresh mozzarella or feta would work well.
    • Dressing: If you have a favorite way to make a balsamic vinaigrette dressing, give that a try for this salad. For even more convenience, bottled balsamic vinaigrette dressing works great. #nojudging #stillcountsashomemade

    💭Did you know?

    You probably know that tomatoes are actually a fruit. But did you realize that that same is true of cucumbers? Because a cucumber grows from the flower part of a plant, it is botanically considered a fruit. Which makes it just another in a long list of veggies that are actually fruits. We probably need a whole new classification system for these. Fregetables, maybe?
