Wash the spring mix salad greens and butter lettuce thoroughly under cold water. Use a salad spinner to dry them well and place in a large mixing bowl.

Gently toss in the fresh blueberries, crunchy pistachios, diced avocado, thinly sliced watermelon radish, and finely chopped red onion. Sprinkle feta cheese on top.

In a small bowl, combine the creamy pomegranate dressing ingredients: pomegranate juice, honey, vinegar, and olive oil. Whisk until well-blended and creamy.

Drizzle the dressing over the salad just before serving. Toss lightly to coat without bruising the greens.
