Use a knife and cutting board to cut the watermelon flesh into small cubes. Transfer the cubes to a food processor or blender and pulse briefly until slightly broken down but not fully pureed, to maintain some texture.
Spread the watermelon seeds onto a baking sheet or plate. Use a rolling pin or the bottom of a glass to crush the seeds into coarse crumbs. Set aside.
In a small bowl, combine the crushed watermelon seeds with the watermelon pulp. Mix gently to incorporate some seed crumbs throughout the fruit.
Arrange the watermelon mixture on a plate or shallow dish, creating a roughly layered or piled presentation. Drizzle honey evenly over the top, allowing it to seep into the fruit and seeds.
Optional: Sprinkle finely chopped mint over the top as a garnish for added aroma and color. Serve immediately to enjoy the juicy, crumbly textures.
