Begin by selecting a ripe watermelon. Slice off the rind and cut into bite-sized cubes. Place in a large mixing bowl.

In a small bowl, whisk together olive oil, lime juice, lime zest, sweetener, kosher salt, and black pepper until well combined.

Pour the dressing over the watermelon and add torn fresh mint leaves. Toss gently to coat.

Let the salad sit for a few minutes at room temperature. Serve garnished with flaky sea salt.
