- Peel and cut the watermelon into 1-inch cubes using a chef's knife on a cutting board. Arrange the cubes in a large mixing bowl. 
- Crumb the feta cheese into small pieces and sprinkle evenly over the watermelon cubes. 
- Roughly chop the fresh mint leaves and add them to the bowl with the watermelon and feta. 
- Using a citrus juicer or reamer, extract the juice from the lime. Pour the lime juice over the salad, then toss gently with a large spoon until all ingredients are evenly coated. 
- Inspect the salad, ensuring the feta and mint are well-distributed, and the watermelon is coated with lime juice. Serve immediately for the freshest flavor and crisp, refreshing texture.
