In a large skillet, heat the olive oil over medium heat.
Add the diced chicken to the skillet and season with salt, pepper, and oregano. Cook for about 5-7 minutes or until the chicken is browned and cooked through. Remove the chicken from the skillet and set aside.
In the same skillet, add the chopped onion and garlic. Sauté for 2-3 minutes until fragrant and translucent.
Add the diced zucchini and red bell pepper to the skillet. Sauté for an additional 5 minutes until the vegetables begin to soften.
Stir in the orzo pasta, mixing well with the vegetables.
Pour in the chicken broth and bring the mixture to a boil.
Reduce the heat to a simmer and add the lemon juice and zest.
Cover and cook for about 10 minutes, stirring occasionally, until the orzo is tender and has absorbed most of the liquid.
Return the cooked chicken to the skillet and stir to combine.
Taste and adjust seasoning with more salt, pepper, or lemon juice as desired.
Garnish with chopped parsley before serving.
