Put the salmon on a foil lined baking sheet and season with a drizzle of olive oil and a sprinkle of coarse salt. Bake for 20 minutes, or until the fish flakes with a fork.
While the salmon is baking whisk together your dressing (be sure to give it a taste to adjust any of the ingredients.)
Put all the salad ingredients ~ except the arugula ~ together in a wide shallow bowl and toss with a little of the dressing.
To serve put some arugula on each plate or bowl, top with the salad and then the salmon, drizzled with more dressing.
