Steps
1. Preheat the oven to 375°F (190°C).
2. Carefully butterfly the chicken breast, creating a pocket for the stuffing.
3. In a bowl, mix together the crumbled cheese, minced garlic, chopped onion, and spinach leaves. Season with salt and pepper.
4. Stuff the chicken breast with the cheese and spinach mixture, then secure with toothpicks.
5. Heat olive oil in an oven-safe skillet over medium-high heat. Add the stuffed chicken breast and sear until golden brown on all sides.
6. Transfer the skillet to the preheated oven and bake for about 15-20 minutes, or until the chicken is cooked through.
7. Remove the toothpicks and serve the Arab chicken and spinach stuffed with cheese with your favorite side dish or salad.
