Pat the salmon dry and season lightly with salt and pepper on both sides.
Heat a non-stick skillet over medium-high heat. Sear the salmon skin-side down first for about 3-4 minutes, then flip and cook for another 3-4 minutes until the fish is cooked through but remains moist.
Meanwhile, steam the green beans until crisp-tender, about 4-5 minutes. Once done, toss them with 1 teaspoon of olive oil, and season with salt and pepper to taste.
Peel and cut the russet potato into chunks. Boil in lightly salted water until tender, approximately 15 minutes.
In a small saucepan, lightly sauté the minced garlic (or crushed garlic clove) in the unsalted butter for about 1 minute. Drain the potatoes and return them to the pot.
Mash the potatoes and garlic mixture together, slowly incorporating the skim milk until smooth and creamy. Season with salt and pepper.
Plate the seared salmon alongside a serving of garlic mashed potatoes and a side of steamed green beans.
Serve immediately while hot, and enjoy your balanced and flavorful meal.
