Calling all of my healthy home cooks!! One tip I learned while studying to become a certified health and weight loss coach is that what grows together goes together. And this is precisely why a tomato and cucumber salad tastes SO good.

Pretty much anything that grows in the same season will pair well from a culinary perspective (hello, tomato salad with green beans and tomato salad with zucchini! It’s like Mother Nature has done all the guesswork for us, so all we have to do is assemble the goods.

Plus, I love when Summer rolls around and I don’t need to turn on the oven because I can make simple salads like this one to enjoy as a light meal. Adding avocado is not only delicious, but it gives this tomato and cucumber salad a little more staying power.

It also makes a fabulous side dish that won’t weigh you down like mayo-based salads sometimes can. I’ll often make a big batch and scoop it onto plates next to grilled chicken, burgers, or even enjoy it as a dip with tortilla chips.

It’s the kind of side that makes you feel good about what you’re eating. Just fresh, simple ingredients doing their thing. If you’re anything like me, once you try it, you’ll be making it on repeat until the last tomato of the season disappears.

Ingredients You’ll Need

You don’t need much to make this awesomely delicious summer salad! Here’s a sneak peek of the ingredients:

Tomatoes and fresh herbs near avocados, lemons and bowls of cucumbers, olive oil and red onion.

Tomatoes: Choose ripe but firm tomatoes for the best flavor and minimal mess. Heirloom or vine-ripened varieties add extra sweetness and color.
English cucumber: These have thin skin and minimal seeds, so no peeling required, just chop and toss.
Red onion: Adds sharpness and crunch. Slice it very thin, and if you find raw onion too strong, soak the slices in cold water for 5–10 minutes to mellow the flavor.
Avocados: Use just-ripe avocados so they hold their shape when tossed.
Lemon juice & extra virgin olive oil: This simple combo brings brightness and richness. I like to whisk together before drizzling to coat evenly.
Garlic: Adds a subtle punch. Crushing or finely mincing helps it distribute better.
Fresh herbs: Use a mix of what you love—parsley for freshness, basil for sweetness, mint for coolness, or cilantro for zest. Chop just before using for maximum flavor.
Sea salt & pepper: Season to taste at the end to bring out all the fresh flavors. Start with a little and add more if needed.

How to Make Tomato Cucumber Salad

The beauty of this salad lies in its simplicity. It’s essential to choose the freshest, most in-season ingredients available – this is what makes the salad shine.

Chopped tomatoes, cucumbers, red onion and avocado in a large bowl with diced herbs and salt and pepper on top. — Add the veggies, fresh herbs, salt, and pepper to a nice big bowl.

Tossed cucumber tomato avocado salad in a large glass bowl. — Drizzle with olive oil and lemon juice, and then add fresh, crushed garlic. Toss to combine.

It’s quick, easy, delicious, and nutritious. My kind of salad – it’s so good that I’ll sometimes pack it as a light lunch and top it with hard-boiled eggs for a protein boost.

Side Note: These are my go-to containers for meal prep – they are the perfect size.
