Slice the chicken lengthwise into about two-inch wide strips.
Pound the chicken pieces into about three-quarters to one inch thickness.
Pat dry with a paper towel and season on both sides with the salt, pepper, Italian seasoning, onion powder, and paprika.
Heat a large skillet or sauté pan over medium-high heat.
Melt two tablespoons of butter in the heated pan.
Add the minced garlic and cook for about one minute, stirring constantly until fragrant.
Add the chicken to the heated pan and sear for about two minutes per side.
Once the chicken is seared, remove from the pan and set aside on a plate.
Add the remaining tablespoon of butter.
Add the rice and cook to toast it slightly for about one to two minutes, stirring frequently.
Add in the chicken broth and chopped spinach and stir to combine.
Bring the rice and broth to a gentle boil.
Reduce heat to medium-low/low and add the chicken back into the pan.
Cover and allow it to simmer for about fifteen to twenty minutes or until all of the liquid is absorbed and the rice is tender.
Once the chicken and rice is cooked, push the chicken to the side to add the parmesan and stir it to melt into the rice.
Serve topped with more parmesan and freshly chopped parsley!
