Slice cucumbers into ¼-inch thick half-moons. If using regular cucumbers with large seeds, halve lengthwise and scoop out seeds first.
Cut avocados in half, remove pits, and cube into bite-sized pieces.
In a small bowl, whisk together lime juice, olive oil, honey, salt, and pepper until well combined.
In a large mixing bowl, gently combine cucumber and avocado pieces.
Pour dressing over vegetables and toss carefully using a rubber spatula or your hands to avoid mashing the avocado.
Add chopped cilantro and give one final gentle mix.
Let salad rest for 5-10 minutes before serving to allow flavors to meld.
Taste and adjust seasoning with additional salt or lime juice if needed.
