In a blender, combine Greek yogurt, lemon juice, mustard, and olive oil. Add mint, parsley, oregano, salt, and pepper. Blend until creamy and smooth, then set aside.

In a large salad bowl, layer super greens mix and kale. Add strawberries, blackberries, and blueberries. Toss gently to distribute the fruits.

Sprinkle pistachios and pepitas over the salad. Toss gently to mix.

Drizzle the creamy dressing over the salad and toss gently to coat everything evenly.

Transfer to a serving dish and garnish with black pepper or herbs if desired. Serve immediately.
