Place shrimp on a plate and pat dry with paper towels. Sprinkle both sides with 1/2 teaspoon of salt and 1/4 teaspoon of pepper.
Heat a large pan over medium, and add the oil. Once shimmering, add the shrimp and sear on each side until golden and cooked through. Remove shrimp from the pan to a plate and set aside.
To the same pan, add the butter. Once melted, add the garlic and saute until it becomes fragrant.
Add the heavy cream, chicken broth, Italian seasoning, and parmesan cheese. Bring Tuscan sauce to a simmer.
Add the spinach and sun dried tomatoes, and continue to simmer just until the spinach wilts. Remove from heat and stir in the shrimp. Serve warm, over pasta, or with bread, and enjoy!
