- Place the watermelon cubes in a large mixing bowl. Ensure they are evenly spread out for easy mixing later. 
- Peel the avocado with a vegetable peeler, then cut it in half, remove the pit, and slice into thin, even pieces. Arrange the slices on top of the watermelon or set aside. 
- In a small bowl, whisk together the olive oil, fresh lemon juice, honey (or agave), sea salt, and black pepper until the dressing is well combined and slightly emulsified. 
- Pour the dressing over the watermelon and avocado slices. Gently toss with a large spoon or spatula until all ingredients are evenly coated without breaking the avocado slices, visualized by a light sheen on the fruit and a gentle mix. 
- Transfer the salad to a serving plate or bowl. Garnish with additional slices of avocado or a sprig of mint if desired. Serve immediately for maximum freshness and visual appeal.
