Pat the salmon dry, season with salt and pepper, and set aside.
Bring a pan over medium-high heat and add a teaspoon of olive oil.
Once the oil is hot, place the salmon skin-side down and sear for about 3-4 minutes per side until cooked through and golden brown.
In a separate pan, heat a small amount of olive oil and add a minced garlic clove. Sauté briefly until fragrant, then add the green beans. Stir-fry until they are tender-crisp, about 4-5 minutes, and season with salt and pepper.
For the cauliflower mash, steam or boil cauliflower florets until very tender, about 8-10 minutes. Drain well.
Blend the cooked cauliflower with nonfat Greek yogurt, a pinch of salt and pepper, and, if desired, a drizzle of olive oil for extra creaminess. Blend until smooth.
Plate the seared salmon alongside a serving of garlic green beans and a generous scoop of cauliflower mash. Serve immediately.
