Season the salmon fillets with salt, pepper, and a squeeze of lemon juice. Combine the other herbs and spices in a bag, and then rub the fish into them.
Spiralize the zucchini into noodle-like shapes. Set aside.
In a bowl, whisk together yogurt, milk, and arrowroot until smooth. This will be our creamy base.
In a large skillet, heat olive oil over medium heat. Add the minced garlic and chopped shallot. Sauté until fragrant and translucent.
Place salmon fillets in the pan, skin side down. Cook for 3-4 minutes on each side until nicely browned. Remove the salmon from the skillet and set aside.
Deglaze the skillet with white wine, scraping up any browned bits. Pour in the arrowroot powder and yogurt mixture, stirring continuously to avoid lumps. Add chicken stock gradually, stirring constantly.
Stir in grated Parmesan and sundried tomatoes (or roasted red pepper). Season with salt and black pepper. Allow the sauce to simmer until it thickens.
Gently place the cooked salmon fillets back into the skillet, allowing them to soak up the creamy goodness. Add capers for a zesty kick and, optionally, some lemon juice.
Toss in the spiralized zucchini noodles, ensuring they are coated in the creamy sauce.
Serve the Creamy Tuscan Salmon over a bed of zucchini noodles. Garnish with additional Parmesan, fresh herbs, and a pinch of black pepper. Bon appétit!
