Peel and chop gold potatoes into uniform chunks.
Place potatoes in a pot of salted water, bring to a boil, and cook for 12-15 minutes until fork-tender.
While potatoes boil, steam the green beans in a steamer basket over simmering water for 5-7 minutes until vibrant and crisp-tender.
Pat the salmon fillet completely dry with paper towels and season both sides with a pinch of sea salt and black pepper.
Heat avocado oil in a non-stick skillet over medium-high heat until shimmering.
Place salmon in the pan skin-side down and sear for 4-5 minutes without moving it to achieve a crispy texture.
Flip the salmon and cook for an additional 2-3 minutes until the internal temperature reaches 145 degrees Fahrenheit.
Drain the cooked potatoes and return them to the pot.
Mash the potatoes with nonfat Greek yogurt and minced garlic until the consistency is creamy and smooth.
Plate the garlic mashed potatoes, top with the seared salmon, and serve alongside the steamed green beans.
