Start by preheating a non-stick skillet over medium-high heat and set aside a small saucepan for the sweet potato mash.
Peel and dice the sweet potato into cubes. Place them in the saucepan with a splash of water, cover, and boil until tender, about 10-12 minutes.
While the sweet potato cooks, trim the ends off the green beans and mince the garlic.
Season the salmon fillet with a pinch of salt and black pepper on both sides.
When the skillet is hot, add half of the olive oil and sear the salmon for about 3-4 minutes per side until the exterior is crisp and the interior is just cooked through.
In a separate pan, add the remaining olive oil and sauté the minced garlic for about 30 seconds until fragrant, then add the green beans. Sauté for 4-5 minutes until they are tender-crisp, stirring occasionally.
Once the sweet potato cubes are soft, drain any excess water and mash them until smooth. Add a pinch of salt and a drizzle of olive oil to enhance flavor if desired.
Plate the dish by placing a generous portion of sweet potato mash, arranging the sautéed green beans on the side, and topping with the perfectly seared salmon.
Serve immediately and enjoy your flavorful, wholesome dinner.
