In a large skillet over medium heat, add olive oil. Once hot, place the salmon fillets skin-side down. Season with salt and pepper and sear for about 4-5 minutes on each side, until golden and cooked through. Remove salmon from the skillet and set aside.
In the same skillet, add minced garlic and sauté for about 1 minute until fragrant.
Pour in the chicken or vegetable broth and allow to simmer for 2-3 minutes, scraping any browned bits from the skillet.
Stir in the heavy cream and Italian seasoning, cooking for an additional 3-4 minutes until the sauce has thickened slightly.
Add halved cherry tomatoes and fresh spinach, stirring until the spinach is wilted and the tomatoes are heated through.
Return the salmon fillets back to the skillet, spooning the creamy sauce over them. Allow to cook together for a minute.
Remove from heat, garnish with grated Parmesan cheese and fresh basil leaves.
