Pat the salmon fillet completely dry with paper towels and season both sides with sea salt and black pepper.
Heat one teaspoon of olive oil in a non-stick skillet over medium-high heat until shimmering.
Place the salmon skin-side down in the pan and press gently with a spatula for 10 seconds to ensure even contact.
Sear the salmon for 4-5 minutes without moving it until the skin is golden and very crisp.
Carefully flip the fillet and cook for an additional 2-3 minutes until the salmon is just opaque in the center.
Remove salmon from the pan and let it rest on a plate.
In the same skillet or a separate pan, add the remaining half teaspoon of olive oil and the minced garlic, sautéing for 30 seconds until fragrant.
Add the green beans and two tablespoons of water to the pan, then cover with a lid to steam for 3-4 minutes.
Remove the lid and sauté the beans for another 2 minutes until the water has evaporated and the beans are tender-crisp.
Fluff the pre-cooked brown rice and warm it through in the microwave or a small pot.
Plate the brown rice alongside the garlic green beans and top with the seared salmon fillet.
