In a large bowl pat the shrimps dry with paper towel, and mix them with salt, 1 teaspoon Italian seasoning and crushed red pepper flakes.
Melt 1 tbsp. of butter in a large, non-stick skillet on medium heat. Add shrimp and fry for 1-2 minutes on each side, just until it cooks through.
Meanwhile bring a large pot of water to a boil and cook orzo pasta according to the package instructions. Drain, rinse with cold water and set aside.
Remove the shrimps from the skillet and set aside. In the same skillet, add the remaining 1 tbsp. of butter and melt until it just starts to brown. Add onion and garlic and cook until translucent and fragrant.
Once the garlic is cooked, add wine and cook for a couple of minutes. Next add heavy cream and once the liquid is simmering, add cooked orzo, salt and 1 teaspoon of Italian seasoning.
Add crumbled feta cheese and mix with orzo. Now add shrimp back into the skillet and reheat. Serve with chopped parsley.
