First, preheat the oven to 200°C (392°F).
Wash the zucchini and slice it thinly. Sprinkle with salt and crumbled basil. Drizzle with a teaspoon of olive oil. Crumble a clove of crushed garlic on top and toss the slices so that they are evenly seasoned. Set aside while you prepare the meat.
Clean the chicken breast so that there are no bones left. Slice it up. Flatten it thinly with a rolling pin through baking paper or foil. Salt both sides of the slices.
In a small bowl, mix the feta cheese with the sour cream.
Place a slice of zucchini on each chicken breast slice. Spread with the feta cream, then roll up. No need to secure them, just place them tightly next to each other in a heatproof dish.
Pour approx. 0.5 dl of water into the bottom of the heatproof dish and approx. 1 teaspoon of olive oil onto the top of the rolls. Cover with aluminum foil and place in the preheated oven.
After 30 minutes, remove the aluminum foil and bake without it.
After 15 minutes, remove from the oven and place mozzarella slices on each roll. Sprinkle with Italian seasoning (salt, basil, and oregano are also good substitutes), drizzle with a little more olive oil, and return to the oven for another 15 minutes.
When ready, remove from the oven and serve with bulgur salad, which is best prepared the night before.
