Heat a little oil and fry the chicken until golden brown, then set aside on a plate.

In the same pan, without washing it, fry the chopped onion. Sauté over medium heat.

Once the onion is sautéed, add the wine and let it boil a little. Then add the water, and when it boils, add the chicken bouillon cube.

Now add the cheese slices one by one, stirring a little to create the sauce.

Once all the cheese is melted, add the salt and pepper. I also added a little oregano.

Mix everything together and add the chicken fillets, letting them blend with the sauce.

Done! And delicious!
