Peel and dice the sweet potato into small cubes, then steam or boil until fork-tender, about 10-12 minutes.
Drain the sweet potato and mash thoroughly with a pinch of sea salt and black pepper until smooth and creamy.
While the potato cooks, heat half of the olive oil in a non-stick skillet over medium-high heat.
Season the salmon fillet with salt and pepper, then place it skin-side down in the hot skillet.
Sear the salmon for 4-5 minutes until the skin is crispy, then flip and cook for another 3 minutes or until your desired doneness is reached.
Remove the salmon from the pan and set aside to rest.
In the same skillet, add the remaining oil, minced garlic, and green beans.
Sauté the beans for 5-6 minutes until tender-crisp and slightly charred.
Plate the sweet potato mash alongside the green beans and top with the seared salmon.
Finish with a fresh squeeze of lemon juice over the fish for a bright flavor profile.
