- Add sliced bell peppers or mushrooms for extra veggies and texture.
- For a spicy kick, increase red pepper flakes or add a dash of hot sauce before baking.

Storage

Instructions
- Preheat the Oven: Preheat your oven to 375°F (190°C) to ensure it reaches the right temperature for baking the casserole evenly.
- Combine Ingredients: In a 2.5-quart (11×7-inch / 28×18 cm) baking dish, add the chicken breast, sliced zucchini, fresh spinach, halved cherry or grape tomatoes, chopped sun-dried tomatoes, thinly sliced shallot, minced garlic, and olive oil.

- Add Cheese: Evenly sprinkle the shredded mozzarella and grated Parmesan cheese on top of the vegetable and chicken mixture.
- Cover and Bake: Cover the dish tightly with aluminum foil and bake in the preheated oven for 20 minutes. This allows the chicken to cook through and the vegetables to soften.
- Remove Foil and Continue Baking: Remove the foil and bake uncovered for an additional 10 minutes to let the cheese start to brown and the top to set.
- Broil for Golden Cheese: Switch the oven to broil on high and broil the casserole for 1 to 2 minutes. Keep a close eye and check every 20 seconds to prevent burning, allowing the cheese to develop a golden crust.

Notes
- You can substitute chicken thighs for chicken breast if you prefer a juicier texture.
- Sun-dried tomatoes packed in oil add depth of flavor; if using dry-packed, rehydrate them in hot water before use.
- For a lower-fat version, reduce the amount of cheese or use part-skim mozzarella.
- Ensure to watch closely when broiling to avoid burning the cheese topping.
- This casserole can be prepared a day ahead and baked just before serving for convenience.
