Dice your chicken into 1″ chunks and coat in the seasoning salt.
In a large skillet over medium heat, add 1 tablespoon of olive oil. Once the oil is hot, add half of your garlic and all of your chicken. Cook for 5 minutes, stirring frequently and lightly browning the outside of each piece of chicken. Remove chicken from the pan and set aside.
Add the wine and rest of your garlic to the pan and let it come to a slow boil. Cook for 5 minutes.
Add orzo and mix it around with the wine and garlic. Gently cook the orzo for about 1 minute. Add your broth and mix.
Bring to a boil and add chicken on top of the orzo; no need to mix it yet. Lower the heat and cover the pan. Cook for 10 - 15 minutes, stirring once after 5 minutes.
Once orzo and chicken are fully cooked, turn off the heat. Stir in the cheese, half and half, spinach, nutmeg (optional) and a little black pepper and fresh basil according to your preference. If orzo is drier than you want, add a tiny bit of water to loosen up the consistency.
