Heat the olive oil in a large skillet over medium heat. Once hot, add the diced chicken thighs and season generously with salt, pepper, oregano, and paprika. Cook, stirring occasionally, until the chicken is golden brown and fully cooked, approximately 6-8 minutes. Once done, remove the chicken from the skillet and set it aside on a plate.
In the same skillet that retained the flavorful drippings, add the diced onion and minced garlic. Sauté for about 2-3 minutes or until the onion is soft and translucent.
Next, toss in the diced red bell pepper, cooking for an additional 3 minutes until it softens.
Add the orzo pasta to the skillet, stirring it into the mixture so it combines well with the vegetables.
Gradually pour in the chicken broth and bring the mixture to a gentle boil. Once boiling, lower the heat to a simmer, cover the skillet, and let it cook for approximately 10 minutes. Stir occasionally to prevent the orzo from sticking to the bottom.
After 10 minutes, reintroduce the cherry tomatoes and the cooked chicken into the skillet. Stir gently and continue to cook for another 5 minutes, until the orzo is tender and has absorbed most of the broth.
Remove the skillet from the heat and fluff the orzo gently with a fork. Taste the dish and adjust seasoning if needed.
Serve the dish warm, beautifully garnished with freshly chopped parsley and crumbled feta cheese on top, if desired.
