01 - Pour the olive oil into a large skillet and set over medium heat until shimmering.
02 - Add the diced onion to the hot pan and cook for 2–3 minutes until softened and translucent.
03 - Stir in the minced garlic and cook for 30 seconds until fragrant, taking care not to burn.
04 - Add the ground chicken, breaking it apart with a spatula. Cook for 5–6 minutes until fully browned and cooked through.
05 - Mix in the red bell pepper and cherry tomatoes. Cook for 3–4 minutes until the vegetables begin to soften.
06 - Sprinkle in the oregano, smoked paprika, red pepper flakes, salt, and black pepper. Stir thoroughly to distribute the spices evenly.
07 - Add the baby spinach and stir continuously for 1–2 minutes until just wilted.
08 - Scatter the olives and crumbled feta over the skillet. Reduce heat to low, cover, and cook for 2 minutes to warm the cheese and meld flavors.
09 - Remove from heat. Garnish with chopped parsley if desired. Serve hot directly from the skillet.
