Cook orzo according to package instructions. When done, drain and set aside.
In a large skillet over medium heat, add oil and butter. Add chopped onion and season with salt. Cover and cook for a few minutes until onions are tender. Once tender, stir in garlic and spinach and cook another couple minutes.
Add shredded chicken and orzo to the skillet and stir to combine. Stir in caesar dressing, parmesan cheese and black pepper.
Serve with red pepper flakes for added spice and extra parmesan cheese. Enjoy!
*This dish can be served hot or cold and would make an excellent easy lunch on the go.
