Slice the chicken breast into thin pieces. If necessary, you can also pound them slightly. (Count 1 slice per serving.) Sprinkle with salt and pepper, then let rest for 5-10 minutes.
Place the prepared chicken breasts into an ovenproof dish and pre-bake at 200°C (392°F) until they develop a golden-brown color. Turn them once during baking.
Mix the sour cream with crushed garlic and dried basil, then spread it over the roasted chicken slices. Sprinkle with sweet corn, place a slice of ham on each piece, and top with grated cheese.
Place into a preheated oven at 200°C (392°F) and bake for 30 minutes.
Steam the bulgur as a side dish.
Serve with arugula and pickled pearl onions. In my opinion, they make a perfect combination.
