Place honey, grated lemon peel, ground pepper, garlic powder and hot water in a small bowl and whisk until blended. With gloved hands, rub mixture over salmon fillets.
Heat olive oil in a skillet over medium heat. Add spice-rubbed salmon fillets and cook 4 minutes. Carefully turn fillets with a spatula.
Reduce heat to medium-low and cook an additional 4 to 6 minutes, until fish turns opaque throughout and flakes easily when tested with a fork.
Arrange 1/2-cup arugula on each plate. Place salmon fillet on top of arugula and garnish with a sprig of fresh dill.
