In a sauce pan, melt the butter on medium heat. Add the diced yellow onion and saute for 3-4 minutes, (until translucent), stirring frequently. Add the garlic, lemon zest, salt, Italian seasoning, and long grain rice, then mix well. Saute for 1-2 minutes, and then add the chicken broth.
Turn the heat up to high, and bring to a rolling boil. Cover with a lid, and turn the heat down to simmer. Let the rice cook for about 15 minutes, or until all of the liquid is absorbed. Remove from heat.
Fluff the rice with a fork, then mix in the lemon juice and fresh parsley.
Serve the rice with the sliced chicken and vegetables, topped with some parmesan cheese. Enjoy!
