For the chicken & veggies:

2 medium zucchinis, sliced into half-moons

1 medium onion, chopped

3 garlic cloves, minced

2 tbsp olive oil

1 red bell pepper, diced

1 cup cherry tomatoes, halved

1 tsp dried oregano

1 tsp dried basil

½ tsp paprika

Salt & black pepper, to taste

For the casserole base:

½ cup chicken broth

½ tsp chili flakes

1 cup cooked rice, quinoa, or orzo pasta

For topping:

1 cup shredded mozzarella cheese

½ cup crumbled feta cheese

2 tbsp fresh parsley or basil, chopped

Instructions

Preheat oven to 190°C (375°F).

Cook chicken:

Heat 1 tbsp olive oil in a skillet over medium heat.

Season chicken with salt, pepper, oregano, paprika.

Sear until golden (doesn’t need to be fully cooked). Remove and set aside.

Cook veggies:

In the same skillet, add remaining olive oil.

Saute onions, zucchini, bell pepper, and garlic 5–6 minutes until softened.

Stir in cherry tomatoes and season with basil, oregano, salt, and pepper.

Build the casserole:

In a baking dish, combine chicken, sauteed veggies, crushed tomatoes, and chicken broth.

If using rice/quinoa/orzo, mix it in now for a heartier dish.

Taste and adjust seasoning.

Top & bake:

Sprinkle mozzarella and feta evenly on top.

Bake uncovered for 20–25 minutes until bubbly and golden.

Serve:

Garnish with fresh parsley or basil.

Serve warm with a side of crusty bread or a simple green salad.

Notes & Tips

Swap zucchini for eggplant or use both for extra flavor.

For a lighter version, skip the rice/pasta and serve with a fresh salad.

Add olives or artichoke hearts for even more Mediterranean flair.
