In a large pot or Dutch oven, heat the olive oil over medium heat. Add the diced chicken and season with salt and pepper. Cook until the chicken is golden brown, about 5-7 minutes.
Add the chopped onion and minced garlic to the pot. Sauté for another 2-3 minutes until the onion becomes translucent.
Stir in the cherry tomatoes, bell peppers, oregano, basil, and paprika. Cook for an additional 3-4 minutes until the vegetables start to soften.
Add the orzo pasta and chicken broth to the pot. Bring to a boil, then reduce the heat to a simmer. Cover and let it cook for about 10-12 minutes, or until the orzo is tender and most of the liquid is absorbed.
Stir in the fresh spinach and crumbled feta cheese, mixing everything together until the spinach is wilted. Adjust seasoning with salt and pepper if needed.
Remove from heat and let it sit for a few minutes before serving.
Notes
Serve in shallow bowls, garnished with fresh parsley and additional feta.
