Follow these step-by-step instructions to create this amazing Lemon Chicken Orzo dish effortlessly:

1. Prepare the Chicken: Season the chicken breasts with salt and pepper on both sides.
2. Heat Oil: In a large pot or Dutch oven, heat the olive oil over medium heat.
3. Cook the Chicken: Add the chicken breasts to the pot and cook for 5-7 minutes on each side until golden brown and cooked through. Remove and set aside to rest.
4. Sauté Onions: In the same pot, add the diced onion. Sauté for 3-4 minutes until translucent.
5. Add Garlic: Stir in the minced garlic and sauté for another minute until fragrant.
6. Cook Orzo: Add the orzo to the pot, stirring to combine with the onions and garlic.
7. Pour in Broth: Gradually pour in the chicken broth, ensuring the orzo is submerged. Add the lemon juice, zest, and oregano at this stage.
8. Simmer: Bring the mixture to a gentle boil, then reduce the heat. Cover and let it simmer for about 10 minutes until the orzo is tender and has absorbed the broth.
9. Chop Chicken: While the orzo is cooking, dice the cooked chicken into bite-sized pieces.
10. Combine Ingredients: Once the orzo is cooked, stir in the chopped spinach or kale followed by the diced chicken. Let it simmer for an additional 2-3 minutes until the greens wilt.
11. Adjust Seasoning: Taste the dish and adjust the seasoning if necessary. Add more lemon if desired for a fresh zing.
12. Serve: Garnish with fresh parsley before serving.

By following these steps, you will create a delicious Lemon Chicken Orzo that is full of flavor and comfort.
