Layer the Base: In a large, pretty serving bowl, gently combine your cubed watermelon, feta cheese, and fresh blueberries
Add the Freshness: Scatter the chopped fresh mint evenly over the top of the fruit and cheese mixture.
Dress It Up: Squeeze the juice of one fresh lime directly over the salad to wake up all those beautiful flavors.
The Final Touch: Sprinkle a tiny pinch of coarse sea salt over everything to really make that sweet watermelon flavor pop.
Toss and Serve: Give it a very gentle toss so you do not break up the feta too much, and serve it up immediately.
