Season the chicken breasts with salt, black pepper and sweet paprika.
Make a cut in the center of each chicken breast and fil the hole with some aluminum foil to maintain the cut shape even after fried. Do it just like shown in the video.
In a skillet filled with hot oil, add the garlic cloves and the chicken breast, fry them on both sides until golden brown.
Remove from the hot oil and soak the excess fat on a plate lined with paper towels.
Once you’ve done that, in a bowl, add the egg whites, the salt, parsley to taste and mix well until combined. Add the grated cheese and mix once again until incorporated.
In a medium ovenproof dish, place all the chicken breasts and the garlic cloves.
Remove the aluminum foil from the chicken breasts and fill each of them with one tablespoon of the cheesy egg white mixture.
Add the round slices of tomato and take to a preheated oven at 200°C (400°F), and roast for 15 minutes.
After this indicated time, add another 150g of grated cheese all over it and top each chicken breast with 1 egg yolk.
Take the dish back to the oven and let it all bake for another 10 minutes.
Serve.
