Preheat oven to 400 degrees Fahrenheit. Line a baking sheet with parchment paper.
Place salmon fillets skin-side down on the baking sheet.
In a small bowl, mix olive oil, lemon juice, salt, pepper, garlic powder, and dried parsley.
Brush the mixture evenly over each salmon fillet.
Top each piece of salmon with two thin lemon slices.
Toss green beans with olive oil, salt, and pepper, then arrange them beside the salmon on the same baking sheet.
Bake for 12 to 15 minutes, or until the salmon flakes easily with a fork and the green beans are tender-crisp.
Remove from oven and serve hot, garnished with fresh parsley.
