Preheat a non-stick skillet over medium-high heat and add 1 teaspoon of olive oil.
Season the salmon fillet with salt and pepper on both sides.
Place the salmon in the skillet, skin-side down if applicable, and sear for about 4-5 minutes per side until the exterior is golden and the inside reaches your desired doneness.
While the salmon cooks, blanch the green beans in a pot of boiling water for 3 minutes until just tender, then immediately transfer them to a bowl with ice water to halt cooking.
In a separate pan, heat a small amount of olive oil over medium heat and sauté minced garlic until fragrant, then add the green beans and toss to coat with garlic flavor. Season lightly with salt and pepper.
Steam the cauliflower until it is very tender, about 8-10 minutes.
Transfer the steamed cauliflower to a blender or use a potato masher, add 1 tablespoon of olive oil, and blend or mash until smooth. Season with salt and pepper to taste.
Plate the dish by placing a generous serving of cauliflower mash on the plate, top with the seared salmon, and arrange the garlic green beans on the side.
Serve immediately and enjoy your protein-rich, balanced meal.
