Peel and cube the sweet potato, then boil in a small pot of water 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.
Steam or blanch the green beans in boiling water for 3 minutes until bright green, then drain and set aside.
Pat the salmon fillet dry with a paper towel and season both sides with salt and pepper.
Heat the olive oil in a non-stick skillet over medium-high heat.
Place the salmon in the skillet skin-side down and sear for 4-5 minutes until the skin is crispy.
Flip the salmon and cook for another 3-4 minutes until the fish is opaque and flakes easily.
Remove the salmon from the pan and add the minced garlic and blanched green beans, sautéing for 1-2 minutes until fragrant.
Serve the seared salmon over the sweet potato mash with the garlic green beans on the side.
