Start by cutting ripe watermelon into even cubes, feeling for that satisfying crunch, and set them aside in a large bowl.
Crack fresh black pepper and crumble the feta cheese into a separate bowl, aiming for uneven, crumbly pieces that will add texture and flavor.
Roughly chop the fresh mint leaves, gently tearing them to release their aromatic oils, and sprinkle over the watermelon.
Squeeze fresh lemon juice over the watermelon and mint, then drizzle with good-quality olive oil, giving everything a gentle toss to coat evenly.
Add the crumbled feta to the bowl, and carefully fold everything together just until the feta is evenly distributed without crushing the watermelon.
Finish by sprinkling a pinch of flaky sea salt and additional black pepper to taste, adjusting the seasoning to balance the sweetness and saltiness.
Serve immediately on a beautiful platter or individual plates, ensuring the watermelon maintains its shape and the feta stays crumbly for a fresh, crunchy bite.
