Cook orzo according to package directions. Drain and set aside. Heat olive oil in a medium-sized pot over medium heat. Add garlic, salt, and pepper and sauté for 1 minute until garlic is fragrant

Add flour to form and stir for one minute. Add about ¼ cup of the milk to the pot and whisk to work out any lumps. When lumps are gone, add the remaining milk and whisk to combine. Bring to a simmer and cook for about 8 minutes or until sauce is thickened.

Add chopped spinach to sauce. Cook an additional 2 minutes or so until spinach is soft and dark. Remove sauce from heat and stir in parmesan cheese. When cheese has melted, add orzo and stir to combine. Serve with extra parmesan cheese and serve immediately. Enjoy!
