Combine the first 4 ingredients in a large bowl. Add the strawberries and toss to combine. Cover and let the strawberries macerate 20 minutes. Add the salad greens to the bowl and toss to combine with the strawberry mixture. Divide the salad among plates, ensuring some of the strawberries decorate the top of the salad. Divide and top each salad with nuggets of the cheese and walnuts. Serve immediately.
