Prepare the Vegetables: Begin by washing the cucumbers thoroughly. Using a sharp knife, slice them into thin, even rounds for a crisp texture. Next, carefully cut the avocado in half, remove the pit, peel off the skin, and slice the flesh into smooth, uniform pieces. Chop the green onions finely to add a fresh, mild bite.
Combine Ingredients in a Bowl: Place the cucumber slices, avocado pieces, and chopped green onions into a medium-sized mixing bowl. Gently toss the ingredients together to evenly distribute them, taking care not to mash the avocado.
Make the Dressing: In a small separate bowl or directly over the salad, pour in the fresh lime juice and extra virgin olive oil. Sprinkle the sea salt and black pepper over the salad. The acidity of the lime juice will brighten the flavors, while the olive oil adds richness.
Toss and Serve Immediately: Using salad tongs or two large spoons, gently toss all ingredients to coat everything evenly with the dressing. Serve the salad right away to enjoy the fresh flavors and crisp textures at their best.
