Heat 2 tbsp olive oil in a large skillet over medium heat.
Cook 1 lb shrimp until pink and opaque (2-3 minutes per side), then remove and set aside.
In the same skillet, sauté 2 cloves minced garlic for 1 minute.
Add 1/2 cup chopped sun-dried tomatoes and 2 cups fresh spinach, cook until spinach wilts (2-3 minutes).
Pour in 1 cup heavy cream, simmer while stirring occasionally.
Stir in 1/2 cup grated Parmesan cheese and 1 tsp Italian seasoning, simmer until the sauce thickens (5-7 minutes).
Return shrimp to the skillet, stir to coat in the sauce, and cook for 2-3 minutes until heated through.
Serve over cauliflower rice or zucchini noodles.
