Heat the olive oil in a large skillet over medium heat. Add the ground chicken and cook until browned, breaking it apart with a spoon, about 6-8 minutes.
Add the chopped onion and minced garlic to the skillet. Sauté until the onion becomes translucent, about 2-3 minutes.
Stir in the bell pepper, oregano, smoked paprika, cumin, salt, and pepper. Cook for another 3-4 minutes until the bell pepper softens slightly.
Add the cherry tomatoes and olives to the skillet. Mix well and allow the tomatoes to cook down for about 5 minutes.
Sprinkle the crumbled feta cheese over the mixture and let it melt slightly into the skillet.
Remove from heat and stir in the fresh parsley and lemon juice.
Taste and adjust seasoning if necessary. Serve warm.
