For the vinaigrette: Whisk together the olive oil, vinegar, orange juice, orange zest, parsley and some salt and pepper in a small bowl. Refrigerate until ready to serve.
For the salad: Simmer the black-eyed peas in the chicken broth for 5 minutes. Drain and let cool to room temperature. In a large bowl, toss together the black-eyed peas, arugula, cucumbers, onions, pear, currants and red peppers. Toss with half of the citrus vinaigrette. In a separate bowl, toss the shrimp with the remaining dressing. Add the shrimp to the salad. Serve immediately.
