In a large salad bowl, combine the diced mangoes, thinly sliced cucumber, diced avocados, and diced tomatoes.
In a separate bowl, whisk together the freshly squeezed lime juice, extra-virgin olive oil, honey (or maple syrup), salt, and black pepper to create the zesty lime dressing.
Drizzle the dressing over the mango, cucumber, avocado, and tomato mixture, gently tossing the ingredients to ensure they are evenly coated.
Taste the salad and adjust the seasoning or sweetness to your preference by adding more lime juice, salt, pepper, or honey (or maple syrup).
Optionally, garnish the Mango, Cucumber, Avocado, and Tomato Salad with freshly chopped cilantro or mint leaves for added freshness and aroma.
Serve the salad immediately as a side dish to complement grilled meats, seafood, or as a light and flavorful meal on its own.
