Prep the ingredients by mincing garlic and halving cherry tomatoes.

Season the salmon fillets generously with salt and pepper.

Heat olive oil in a skillet over medium-high heat. Sear the salmon for about 5 minutes on each side until golden brown. Remove from skillet and set aside.

In the same skillet, lower heat and sauté minced garlic until fragrant. Add cherry tomatoes and spinach, cooking until spinach wilts.

Stir in heavy cream, dried oregano, and Parmesan cheese; mix until creamy.

Return the salmon to the skillet, simmering for an additional minute before serving.
