In a large mixing bowl, combine bite-sized pieces of seedless watermelon with finely chopped scallions and thinly shaved radishes. Add crumbled feta, fresh basil, and mint leaves. Drizzle in lime juice and ¼ cup of extra virgin olive oil, then add honey to enhance flavors. Gently toss for 1-2 minutes until well combined.

In a large salad bowl, arrange a generous layer of fresh arugula at the bottom. Lightly drizzle with olive oil.

Spoon the watermelon mixture over the arugula, ensuring even distribution of ingredients for a striking presentation.

In a small bowl, mix together roasted pistachios, lime zest, red pepper flakes, and the remaining 2 tablespoons of olive oil. Stir for 30 seconds until well combined.

Spoon the pistachio mixture over the assembled salad and garnish with extra herbs and a sprinkle of black pepper. Serve immediately.
