Cucumber Tomato Salad – Easy summer salads are the perfect side dish and great for potlucks. This cucumber salad is full of cucumbers, tomatoes, onions, and avocado tossed with a light vinaigrette dressing.
I love summer salads. They can be pasta salad, like taco pasta salad, or a lettuce based salad, or even a corn salad. Using fresh produce makes for the best salads. If you can get fresh corn, Southwestern corn salad is definitely a huge hit.
This cucumber salad is a classic for a reason, it is so fresh and delicious. Super ripe tomatoes from the garden make it even better. My family loves anything with avocado, so of course we had to turn it into a cucumber tomato avocado salad.

Sometimes you will see a cucumber salad with just onions in a creamy dressing. Or a vinegar based dressing. Those aren’t my favorite. I like to add lots of fresh tomatoes and a light vinaigrette dressing to make it well balanced and delicious.
I am always looking for different potluck recipes to make in the summer, and salads are usually a huge hit. Something that everyone can eat, is colorful and fresh, plus uses fresh ingredients always wins people over. So it should be no surprises that this cucumber tomato salad disappears quickly every time.

This cucumber salad recipe is pretty basic, you just have to slice the vegetables. I like to cut the tomatoes into bigger chunks, so they don’t get lost. The red onions are very thinly sliced. The cucumbers are thinly sliced, and then I like to cut them into half circles, so they are easier to eat. My son likes avocado added to everything, so I diced those up as well.
Fresh parsley helps bring everything together. You could use cilantro in place of the parsley if you like, both would be delicious. I mix the dressing together in a little jar and shake it like crazy until it is combined. Then just pour it over the salad and lightly toss it together. It is best when it has set for at least an hour, so the dressing blend with the veggies and it all comes together.

Summer salads are great when you can make them ahead of time. Summers are busy, so you don’t want to spend a ton of time in the kitchen before guests arrive, or before you leave for a party. You can definitely make this salad ahead of time, I would just add the avocado about an hour before you are going to serve it. It has a tendency to turn brown and break down some. It won’t be bad if you put it in hours ahead, but for best results I would add it at the end.
I like to serve this cucumber tomato salad with burgers or even a perfectly grilled ribeye. It balances out a heavy meal with something super light and fresh.
