Peel and cube the sweet potato, then boil in water until tender, about 10-12 minutes.
Drain the sweet potato and mash until smooth, adding a splash of water or pinch of salt if desired for consistency.
Heat a non-stick skillet over medium-high heat with half of the olive oil.
Season the salmon fillet with sea salt and black pepper, then sear for 4-5 minutes per side until the skin is crisp and the flesh is flaky.
Remove the salmon from the pan and set aside to rest.
In the same pan, add the remaining olive oil, minced garlic, and green beans.
Sauté the green beans for 3-5 minutes until they are bright green and slightly blistered.
Plate the sweet potato mash, top with the seared salmon, and serve the garlic green beans on the side.
