Creating the Blueberry Pistachio Spring Salad is simple and can be accomplished by following these easy steps:

1. Prepare the Greens: Wash and dry the mixed greens thoroughly. If needed, tear larger leaves into bite-sized pieces.
2. Mix the Dressing: In a small bowl, whisk together the olive oil, balsamic vinegar, honey (or maple syrup), salt, and pepper until emulsified.
3. Combine Salad Ingredients: In a large mixing bowl, add the mixed greens, blueberries, pistachios, crumbled feta (if using), and sliced red onion.
4. Dress the Salad: Drizzle the prepared dressing over the salad and toss gently to combine, ensuring all ingredients are coated evenly.
5. Garnish: If desired, sprinkle freshly chopped herbs over the salad for an extra layer of flavor.
6. Serve Immediately: Transfer the salad to a serving bowl or platter and enjoy right away for the best texture and flavor.
