Follow these simple steps to create your One Pot Chicken Orzo with ease:

1. Heat the Oil: In a large pot, heat the olive oil over medium heat.
2. Cook the Chicken: Add the chopped chicken pieces to the pot. Season with salt and pepper. Cook until browned and cooked through, about 5-7 minutes. Remove the chicken and set it aside.
3. Sauté the Vegetables: In the same pot, add the chopped onion and bell pepper. Sauté for about 3-4 minutes until softened. Then add the minced garlic and sauté for an additional minute until fragrant.
4. Add the Broth: Pour in the chicken broth and bring the mixture to a boil.
5. Add the Orzo and Tomatoes: Stir in the orzo and diced tomatoes. Reduce the heat to a simmer.
6. Return the Chicken: Add the cooked chicken back to the pot and mix well.
7. Season: Sprinkle in the Italian seasoning. Adjust seasoning with additional salt and pepper if necessary.
8. Cook the Orzo: Cover the pot and let it cook for about 10-12 minutes, stirring occasionally until the orzo is al dente and has absorbed most of the liquid.
9. Add Greens: If using, stir in the fresh spinach or kale during the last couple of minutes of cooking until wilted.
10. Serve: Once cooked, remove from heat. Fluff with a fork and let it sit for a few minutes before serving.
