Ingredients Notes

- Cucumbers: Use English cucumbers since they don’t need to be peeled and have very few seeds. Garden cucumbers can be used, but peel them first and remove any large seeds.
- Tomatoes: Use either grape tomatoes or cherry tomatoes. Diced roma tomatoes can be swapped in, but if using another diced tomato lightly drain them before adding them in.
- Avocados: Fresh and firm avocados are best for this recipe. Don’t cut or add the avocados until just before you serve.
- Dressing: Red wine vinegar and olive oil go great with fresh dill. Use white, apple cider, or rice vinegar as an easy swap.
- Mix It Up: Add cheese like feta, blue cheese, Parmesan, or bocconcini balls. Add some color and extra flavor with sliced black olives or some bacon crumbles.
How to Make a Cucumber Tomato Avocado Salad


- Cube avocado and coat with fresh lemon juice.
- Add all other ingredients to the bowl and toss gently (full recipe below).
- Season to taste, chill briefly, and serve immediately.

Keep It Fresh
- Store leftovers in an airtight container in the refrigerator. For the best flavor and texture, enjoy the entire salad on the day it is prepared.
- Freezing is not recommended. For make-ahead preparation, combine the cucumber, tomatoes, onion, herbs, oil, and vinegar. Then add the lemon-coated avocado just before serving.
