01 - In a small bowl, whisk together the olive oil, lemon juice, honey or maple syrup, Dijon mustard, salt, and pepper until emulsified and smooth.
02 - In a large salad bowl, gently toss the spring greens, blueberries, cucumber slices, and diced avocado until evenly distributed.
03 - Drizzle the dressing evenly over the salad and toss lightly to coat all ingredients without bruising the greens.
04 - Sprinkle the salad with pistachios and crumbled feta cheese, distributing evenly across the top.
05 - Serve immediately, garnished with additional blueberries or pistachios if desired. For best results, dress just before serving to maintain crispness.
