Season the salmon fillet lightly with salt and pepper.
Heat olive oil in a non-stick skillet over medium-high heat.
Sear the salmon, skin side down if applicable, for about 4-5 minutes per side until cooked through and crispy on the outside.
In another pan, heat a small amount of olive oil and sauté the minced garlic until fragrant.
Add the green beans to the pan, and toss with garlic, salt, and pepper. Sauté until tender-crisp, about 4-5 minutes.
Warm the mashed sweet potato, either on the stove or in the microwave, until heated through.
In a small bowl, mix the nonfat Greek yogurt with lemon juice and a pinch of salt to create a tangy sauce.
Plate the salmon alongside the garlic green beans and sweet potato mash, then drizzle the lemon yogurt sauce over the salmon or serve on the side.
Serve immediately and enjoy your nutritious, well-balanced dinner.
