Mix the dressing ingredients together, then place the bowl in the fridge while you prepare the rest of the salad.
Heat the oil in a small pan over medium heat. Add the panko, parmesan cheese, Italian seasoning, garlic powder, salt, and pepper and mix well. Continue to mix until the panko is golden brown and crispy and then remove the pan from the heat.
Add the arugula to a salad bowl and pour enough of the dressing over top to lightly coat the greens - about half. Add half of the crouton crispies and the shaved parmesan and toss gently to coat. Sprinkle the rest of the crouton crispies over top and serve right away.
