This healthy Avocado Tomato Onion Cucumber Salad recipe is light, fresh, and ready in minutes! Good side dish for potlucks or summer picnics and is Vegetarian + Vegan + Whole30 + Paleo + Keto.

I make this avocado cucumber salad at least twice a week. Our family loves it, and it's so easy to make. It’s just a matter of chopping up your veggies and tossing them together in a bowl. Salads like this one and my cucumber salad with yogurt dressing are easy to whip up, don’t require any cooking, and come together in 15 minutes.
I also like to add canned or cooked chickpeas and mixed greens to this salad to make it more healthy and protein-rich. Check my favorite chickpea cucumber salad recipe on my blog.

Ingredients

- Avocado: Be sure to use a good quality ripe avocado but not a mushy or too firm texture for this recipe. I have used 1 Hass Avocado.
- Cucumber: Choose cucumbers with low-seed or seedless variety. I like to use English cucumber for this recipe. Persian cucumbers work too.
- Tomatoes: Grape or cherry tomatoes are my favorite, but diced regular, or Roma tomatoes also work well. They add sweetness and acidity to the dish.
- Onion: red onion works best in salads, so that’s what I used. If you don't like it, feel free to substitute green onions instead.
- Herbs: Fresh Cilantro is a must for this recipe. If you don't have cilantro feel free to use dill leaves, parsley, or basil instead.
- Extra-Virgin Olive oil: a good quality extra virgin olive oil is a must as it brings out flavors.
- Lime juice: Be sure to use fresh lime/lemon juice if you can, which has the best flavor and adds a bit of tang.

How to Serve Avocado Cucumber Salad
This simple salad makes a great side dish and pairs with any main dish. A few suggested pairings are
- Alongside Soups
- Burgers
- Pasta
- Proteins like grilled Paneer Tikka, Crispy Tofu
- Roasted Potatoes
- Cilantro Lime Rice and Mexican Black Beans
Make Ahead and Storage
- Make-Ahead: You can prep the veggies (except for avocado), herbs, and dressing a day before serving. When you’re ready to serve, cut the avocado and toss the veggies, herbs, and dressing together.
- Storage: This avocado salad is best enjoyed when served fresh. Leftover salad will keep in the refrigerator for up to 24 hours when stored in an airtight container. After that, avocados will be quite brown.
Tips for the best Avocado Salad
- Use firm, ripe avocados: Choose good quality ripe avocados but not mushy, otherwise, they will get squishy in the salad.
- Cut veggies into the same size: Cutting into the same sizes improves the visual appeal of the salad and also ensures that all the flavors make it into each forkful.
- Prepare with fresh ingredients: Choose fresh ingredients like veggies, herbs, and lime juice for the best flavor.
- Be gentle while tossing the salad: Toss the salad gently with a spoon so that you don't mash the avocados.
Popular Substitutions & Additions
- Add other vegetables: Try adding other vegetables of your choice, like bell peppers, sweet corn, carrots, olives, green onions, or radishes.
- Cheese: Add some crumbed or cubed feta cheese just before serving for a Mediterranean touch. You may also add baby mozzarella.
- Substitute other fresh herbs: If you are not a fan of cilantro, then try other fresh herbs like dill leaves, parsley, basil, or mint.
- Greens: Try adding some greens like romaine lettuce, baby spinach, kale, or arugula.
- Protein: Add ½ of canned or cooked chickpeas, and edamame for extra protein.
