Toss the watermelon and cucumber together in a large bowl. Sprinkle the cheese on top and season with olive oil, lime juice and black pepper. Sprinkle the chiffonnade of mint leaves over the top of the salad as a garnish.

The colors of the salad look best before tossing, so if you’re making this for company, I recommend serving like this and tossing at the table. Alternatively, you can toss the watermelon and cucumber with the oil, lime juice, salt and pepper and then add the cheese and mint at the end.
