Preheat the grill to medium heat. Brush the Jumbo Shrimp with olive oil and season with salt and pepper. Cook 2 – 3 minutes per side and chill. Whisk together the citrus juice, soy sauce, jalapeno, cilantro, and olive oil until combined. In a large bowl place the arugula, shrimp, peanuts, and vinaigrette. Toss to combine. Place the salad on a plate and garnish with sliced green onions and thin slices of papaya.
