Salt and black pepper to taste

1/2 cup chicken or vegetable broth

1 sprig rosemary

1 carrot, peeled and grated

1 onion, sliced

2 bell peppers (any color), sliced

2 tomatoes, chopped

100 ml water

150 g champignon mushrooms, sliced

2 tablespoons ketchup

1 teaspoon Italian herbs

2 green onions, chopped

For the Fresh Salad:

1 cucumber, sliced

10–12 cherry tomatoes, halved

1/2 red onion, thinly sliced

Salt and pepper to taste

2 teaspoons mayonnaise

1 teaspoon dill, chopped

1 tablespoon green onions, chopped

Step-by-Step Cooking Directions
1. Start the Sauce Base
In a skillet over medium heat, add 1 tablespoon vegetable oil and 1 tablespoon butter. Sauté chopped red onion until soft, then add minced garlic and chili pepper. Cook for 1–2 minutes until fragrant.

2. Add Tomato Flavor
Stir in the tomato paste, sugar, and soy sauce. Mix well and cook for another 2 minutes until the paste caramelizes slightly. Remove from heat and set aside.

3. Prepare the Chicken Fillets
In another pan, heat the remaining oil and butter. Season chicken fillets with salt and black pepper, then sear on both sides until golden brown but not fully cooked through. Remove and place in a baking dish.

4. Build the Sauce Layers
In the same skillet, sauté garlic and rosemary for 1 minute. Add grated carrot, sliced onion, and bell peppers. Cook until slightly softened.

5. Add Tomatoes and Mushrooms
Stir in the chopped tomatoes, water, and a pinch of salt. Add sliced champignons and ketchup. Season with more salt, pepper, and Italian herbs. Simmer until the vegetables are tender and sauce thickens slightly.

6. Combine and Bake
Pour the sauce over the chicken fillets in the baking dish. Sprinkle chopped green onions on top. Cover with foil and bake in a preheated oven at 180°C (360°F) for 25–30 minutes, until the chicken is fully cooked and tender.

7. Make the Side Salad
In a bowl, combine cucumber slices, cherry tomato halves, and thinly sliced red onion. Season with salt and pepper. Stir in mayonnaise, dill, and chopped green onion. Mix gently and chill until ready to serve.

8. Serve and Enjoy
Plate the chicken fillet with a generous spoonful of sauce and a side of the creamy salad. Garnish with extra herbs or lemon zest if desired.
