Place the sliced red onion in a small bowl and cover it with cold water. Let it sit for a few minutes. This softens the sharp taste and makes it sweeter.

In a small bowl or measuring cup, combine the fresh lemon juice, olive oil, honey, minced garlic, salt, and black pepper. Whisk until the dressing looks smooth and blended.

In a large salad bowl, add the chopped cucumber, halved tomatoes, diced avocado, half of the crumbled feta, and the fresh herbs.

Drain the onion slices and gently pat them dry. Add them to the salad bowl. Pour the dressing over the salad ingredients and toss everything together with a light hand so the avocado stays intact.

Sprinkle the remaining feta cheese on top for a pretty final touch. Serve the salad right away while the veggies are crisp and the flavors taste bright.
