In a large bowl, combine the diced cucumbers, avocados, red onion, and cilantro.
In a small bowl or jar, whisk together the lime juice, olive oil, honey, salt, and pepper until well combined.
Pour the dressing over the cucumber and avocado mixture.
Gently toss everything together until evenly coated, being careful not to mash the avocados.
Let the salad sit at room temperature for 10 minutes to allow the flavors to meld.
Taste and adjust seasoning with more salt or lime juice if needed.
Serve immediately, garnished with extra cilantro or lime wedges if desired.
