Preheat your oven to 400°F (200°C).
Toss the cubed sweet potatoes with half of the avocado oil and a pinch of sea salt, then spread them on a baking sheet.
Roast the sweet potatoes for 20-25 minutes until tender and slightly browned.
While potatoes roast, heat a non-stick skillet over medium-high heat and lightly coat the salmon with a tiny drop of oil and salt.
Place the salmon skin-side down in the hot pan and sear for 4-5 minutes until the skin is crisp, then flip and cook for another 3 minutes.
Remove the salmon from the pan and let it rest.
In the same skillet, add the remaining oil and the minced garlic, sautéing for 30 seconds until fragrant.
Add the green beans to the skillet with a splash of water, cover, and steam-sauté for 4-5 minutes until bright green and tender-crisp.
Plate the salmon alongside the roasted sweet potatoes and garlic green beans, finishing the fish with a fresh squeeze of lemon juice.
