Pat the 6 oz salmon fillet dry and season both sides with salt and pepper.
Heat a non-stick skillet over medium-high heat and add the olive oil.
Place the salmon fillet skin-side down in the hot skillet and sear for about 3-4 minutes until a golden crust forms, then flip and cook for another 3-4 minutes until the fish is opaque and flakes easily.
While the salmon cooks, steam the green beans until tender-crisp, about 4-5 minutes.
In a separate pot, steam the cauliflower florets until soft, roughly 8-10 minutes.
In a small pan, lightly sauté the minced garlic (from 2 garlic cloves) in a tiny bit of water or additional olive oil until fragrant, then stir into the steamed cauliflower and mash with a fork or blender until creamy. Season with salt and pepper.
Toss the steamed green beans with the sautéed garlic, salt, and pepper.
Plate the salmon alongside a serving of garlic green beans and a scoop of cauliflower mash, and enjoy your balanced, flavorful dinner.
