In a large pot over medium heat, heat the olive oil. Cook the onions until soft and translucent, about 5 minutes. Add the garlic and cook until fragrant, about 30 more seconds.
Add the cubed chicken and season with Italian seasoning, ½ teaspoon salt, and black pepper. Cook until the chicken is mostly cooked through, about 7 minutes.
Add the rice and cook with the chicken for about 2 minutes. Add the peas, carrots, soy sauce, and remaining ½ teaspoon salt.
Add the water and mix all the ingredients together. Bring to a boil, then reduce the heat to low and cover with a tight-fitting lid. Simmer until the rice is fully cooked, about 15 minutes. Remove from heat and allow the steam to continue cooking the rice for 5–10 more minutes.
Fluff the rice with a fork, sprinkle with fresh parsley if desired, and serve warm.
