This easy cucumber tomato onion salad is a delicious, refreshing side dish perfect for easy meals and great for summer.

This salad has been on our dinner table since I was a little girl. My mom loved a quick, simple salad to serve with dinner and I have continued that tradition with my family. My kids love salad, in all shapes and forms. A meal just isn’t complete without some form of vegetable dressed with a simple vinaigrette.

Ingredients needed

Cucumber.I used English Cucumbers but Persian cucumbers can also be used.
Tomatoes.Use any ripe, in-season juicy tomatoes. Cherry tomatoes, grape tomatoes, beef steak tomatoes, heirloom tomatoes, etc.
Red onion.White onion/Vidalia onion can be used as substitute.
Extra-virgin olive oil.
Lemon juice / Vinegar.
Oregano.I used dried oregano but fresh herbs like basil, chives or fresh dill can also be used.
Salt and black pepper.

How to make cucumber tomato onion salad

Because this recipe is so easy, use the very best ingredients you can afford. Fresh, in season vegetables are a must. Peel and slice the cucumber into coins then add to a large bowl. Slice the tomato into wedges (or halve smaller tomatoes) and thinly slice the red onion then add to the bowl. Dress with a dressing of your choice and serve.

How to make easy salad dressing

Pour equal amounts olive oil and vinegar or lemon juice into a jar then add salt and pepper and dried oregano or whisk together all the ingredients in a small bowl. You can add some minced garlic too. Seal the jar and shake until the dressing is emulsified then pour over the salad.

Can I make this ahead?

Cucumber salad has a tendency to become watery if made too far in advance. You could prepare the ingredients up to 3 hours in advance then cover and keep in the fridge until you’re ready to serve. Pour over the dressing right before serving.

I think I’m switching how I eat cucumbers from now on! Changed herbs to chives and parsley because family dinner, sunflower oil instead of olive oil, because it’s what I had, but amazing! My son-in-law is a picky eater, but he loved it too!

I have this with your greek chicken. No flatbread and a simple balsamic vinegar with salt and pepper. No oil. I have a suit I need to fit into that is 5 years old and 3 chest/waist sizes smaller so being good. I dont feel like I am mising out with your recipes. A little tweak here and there and they are spot on for a low calorie diet too.
