Use a sharp chef's knife to carefully chop the watermelon into 1-inch cubes on a cutting board, ensuring all pieces are uniformly sized for even mixing.
Repeat the process with the pineapple, slicing and dicing into similar-sized chunks to match the watermelon pieces.
Transfer the chopped watermelon and pineapple into a large mixing bowl, gently tossing to combine the fruits evenly.
If desired, drizzle honey over the fruit mixture and sprinkle with a pinch of salt, then toss gently to distribute evenly.
2 cups watermelon
Chill the salad in the refrigerator for at least 10 minutes to allow flavors to meld and serve in individual bowls, garnished if desired.
