The chicken breast fillets are seared on both sides in hot oil in a pan. Season with salt and pepper. Meanwhile, peel the onion and cut it into small cubes. Peel and press the garlic. Then mix both with the feta cheese. Put the meat in a baking dish and then generously cover with the feta mixture.
Bake in the preheated oven at 180 ° C until the cheese has a golden brown color.
