Ingredients
- 2 lbs boneless, skinless chicken breasts (cut into chunks)
- 2 tbsp olive oil
- 1 large onion, diced
- 3 garlic cloves, minced
- 2 cups baby spinach
- 1 cup cherry tomatoes, halved
- ½ cup kalamata olives, pitted and sliced

- Juice and zest of 1 lemon
- 1 tsp dried oregano
- ½ tsp dried thyme

- Fresh parsley, for garnish

Step-by-Step Instructions
Step 1: Prep the Chicken
- Preheat your oven to 375°F (190°C).
- Season chicken chunks with salt, pepper, oregano, and thyme. Heat olive oil in a skillet and sear chicken on all sides until lightly golden (they don’t need to be fully cooked yet).
Step 2: Build the Flavor Base
- In the same skillet, sauté onions and garlic until fragrant. Add spinach and cherry tomatoes, cooking just until spinach wilts and tomatoes soften.
Step 3: Assemble the Casserole
- Spread the seared chicken in a greased 9×13 casserole dish.
- Layer with the spinach-tomato mixture, kalamata olives, lemon juice, and zest.
- Sprinkle feta cheese generously over the top. For extra cheesiness, add shredded mozzarella.
Step 4: Bake to Perfection
- Cover with foil and bake for 25 minutes.
- Remove foil and bake an additional 10–15 minutes, until cheese is melted and casserole is bubbling.
Step 5: Garnish & Serve
- Sprinkle with fresh parsley and serve hot with warm pita bread, couscous, or roasted potatoes.

Variations & Tips
- Make it low-carb: Skip starchy sides and serve with cauliflower rice.
- Add more veggies: Bell peppers or zucchini work beautifully.
- Make it creamy: Stir in ½ cup Greek yogurt before baking for a tangy, creamy texture.
- Meal prep tip: Divide into portions and refrigerate up to 4 days. Freezes well for 2 months.
