Rinse the salmon fillet and pat dry with paper towels.
Season both sides of the salmon with salt and pepper.
Heat the olive oil in a non-stick skillet over medium-high heat.
Once the oil is shimmering, place the salmon fillet skin-side down (if applicable) and sear for about 4-5 minutes until a golden crust forms.
Flip the salmon and cook for an additional 3-4 minutes, depending on thickness, until the center is just opaque.
While the salmon is cooking, steam or blanch the green beans until tender-crisp, about 4 minutes.
In a small pan, lightly sauté minced garlic in a tiny splash of olive oil for about 1 minute until fragrant; toss the green beans in the garlic.
Reheat the pre-cooked brown rice if necessary or serve it warm alongside the salmon and green beans.
Finish by squeezing a lemon wedge over the salmon and green beans for a fresh burst of acidity.
Plate the salmon, green beans, and brown rice together, and serve immediately.
