In a large pot, heat olive oil over medium heat. Add the diced chicken thighs and season with salt and pepper. Cook until browned and cooked through, about 5-7 minutes. Remove chicken from the pot and set aside.
In the same pot, add the minced garlic and diced onion. Sauté for 2-3 minutes, or until the onion becomes translucent and aromatic.
Stir in the orzo pasta and cook for 1-2 minutes, allowing it to toast slightly.
Pour in the chicken broth, lemon zest, lemon juice, oregano, and thyme. Stir to combine, and bring to a gentle boil.
Reduce the heat to low, cover the pot, and simmer for about 10-12 minutes, or until the orzo is al dente, stirring occasionally to prevent sticking.
When the orzo is cooked, add the cherry tomatoes and spinach, along with the previously cooked chicken. Stir well to combine and allow the spinach to wilt, about 2 minutes.
Taste and adjust seasoning with additional salt and pepper if needed.
Remove from heat and let sit for a few minutes to absorb any remaining liquid.
Notes
Serve the orzo in bowls, garnished with freshly chopped parsley and an extra lemon wedge on the side for a pop of color.
