Preheat your oven to 425°F (220°C).
Wash and dice the gold potato into 1-inch cubes. Toss with half the olive oil, a pinch of salt, and pepper.
Spread the potatoes on a baking sheet and roast for 25-30 minutes until they are crispy on the outside and tender inside, stirring once halfway through.
While the potatoes roast, prepare the salmon by patting it dry, seasoning with salt, pepper, and a squeeze of lemon juice. Finely mince the garlic clove and sprinkle it over the fish.
Heat a nonstick skillet over medium-high heat with a little olive oil. Place the salmon skin-side down and cook for about 4 minutes per side, depending on thickness, until the outside is crisp and the fish is cooked to your liking.
For the green beans, trim the ends and toss them with the remaining olive oil, salt, and pepper. In the same skillet used for salmon (or a separate large pan), add the green beans and blister them over medium-high heat for about 5-7 minutes until they are tender with charred spots.
Once everything is cooked, plate the roasted potatoes, place the lemon-herb salmon on top, and arrange the blistered green beans on the side.
Finish with a drizzle of lemon juice and a sprinkle of fresh parsley over the salmon and green beans for an extra burst of flavor.
