Start by chopping the watermelon into thick, juicy cubes. Use a sharp knife to ensure clean cuts, and place the cubes on a serving plate.
Crumble the feta cheese with your fingers right before assembling—this keeps it crumbly and prevents it from becoming mushy.
Sprinkle the crumbled feta evenly over the watermelon cubes, distributing it generously but gently so it stays crumbly.
Scatter torn fresh mint leaves over the salad for a fragrant, cool aroma that instantly brightens the dish.
In a small bowl, whisk together the olive oil and lemon juice until well combined; this creates a simple, zesty dressing.
Drizzle the dressing evenly over the watermelon and feta, allowing the flavors to mingle naturally.
Finish by cracking freshly ground black pepper over the top and sprinkling a pinch of flaky sea salt for extra flavor.
Gently toss the salad with a spoon to combine all the ingredients without breaking the watermelon cubes.
Serve immediately on the plate, allowing the fresh, juicy texture and bright flavors to shine through.
