For the tomato and melon salad, peel the melons and cut into cubes. Cut the tomatoes into wedges. Season both with a little salt and let stand in a bowl for 10 minutes.
Meanwhile, prepare the dressing: to do this, mix the lime juice and grated lime with the honey and slowly pour in the olive oil. Season to taste with salt and pepper. Pluck the mint from the stems and mix with the dressing in the tomato and melon salad.
