Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Toss the cubed sweet potatoes with half of the avocado oil and a pinch of sea salt, then spread them in a single layer on the baking sheet.
Roast the sweet potatoes for 20-25 minutes, tossing halfway through, until they are tender and caramelized.
While the potatoes roast, season the salmon fillet with sea salt and black pepper.
Heat the remaining avocado oil in a non-stick skillet over medium-high heat.
Place the salmon in the pan, skin-side down, and sear for 4-5 minutes until the skin is crispy.
Flip the salmon carefully and cook for an additional 2-3 minutes until cooked to your preferred doneness, then remove from the pan and let rest.
In the same skillet, add the green beans and minced garlic, sautéing for 4-5 minutes until they are bright green and crisp-tender.
Plate the seared salmon alongside the roasted sweet potatoes and garlic green beans, serving immediately.
