Prep the Greens: In a large, beautiful salad bowl, place your pre-washed mixed greens, creating a fresh, light bed.
Combine the Salad: Layer the prepared radishes, apple, orange pieces, grated carrot, and red onion over the greens.
Prepare the Vinaigrette: In a small glass jar or a cocktail shaker, combine all vinaigrette ingredients. Close tightly and shake vigorously until completely emulsified.
Assemble and Serve: Just before serving, pour the vinaigrette over the salad. Top generously with the toasted walnuts and toss gently to ensure everything is evenly coated. Serve immediately for maximum freshness and crunch.
