Marinate the Chicken: In a small bowl, mix olive oil, oregano, paprika, salt, black pepper, minced garlic, and lemon juice. Coat the chicken breasts evenly with the marinade and let them sit for 15-30 minutes.
Cook the Chicken: Heat a large skillet over medium heat. Add the marinated chicken and cook for 5-6 minutes per side until golden brown and fully cooked. Remove from heat and let the chicken rest for a few minutes before slicing.
Prepare the Orzo: In the same pan, heat olive oil over medium heat. Add the orzo and toast for 1-2 minutes until slightly golden. Pour in the chicken broth, add salt and pepper, and bring to a boil. Reduce the heat and let it simmer for about 10 minutes, stirring occasionally, until the orzo is tender and absorbs the liquid.
Assemble the Dish: Place the cooked orzo on a plate or serving dish. Slice the chicken and arrange it on top. Add halved cherry tomatoes, sliced Kalamata olives, and crumbled feta cheese.
Garnish and Serve: Drizzle with lemon juice and sprinkle fresh parsley over the top. Serve immediately and enjoy.
