Preheat your oven to 400°F (200°C).
Place the salmon fillets on a baking sheet lined with parchment paper.
Drizzle olive oil over the fillets and season with salt and pepper to taste.
Top each fillet with slices of lemon for an extra zesty flavor.
Bake in the preheated oven for about 12-15 minutes, or until the salmon flakes easily with a fork.
While the salmon is cooking, heat a pan over medium heat, and add a splash of olive oil.
Sauté the minced garlic until fragrant, and then add the spinach.
Cook until the spinach is wilted, about 2-3 minutes.
Serve the baked salmon alongside the sautéed spinach for a nutritious and delightful meal!
