Prepare ingredients for chops with pickled cucumbers. Cut the chicken fillet into three equal parts. Cut pickled cucumbers into slices. Peel the onion and cut into rings. Grind half of the processed cheese, cut the rest into cubes.
Prepare the chicken fillet. Beat the poultry meat so that the thickness of the pieces becomes 5-8 mm. Rub with salt and herbs de Provence on both sides. Spread with mustard. Place slices of pickled cucumbers on the prepared fillet. Then distribute the onion rings evenly.
Make the cheese sauce. Mix the egg with salt and sugar. Add oil and vinegar. Beat the mixture with a blender until white. Add shredded processed cheese.
Prepare chops with pickled cucumbers. Place foil on a baking sheet. Place chicken fillet with filling on it. Top with cheese sauce. Place melted cheese cubes on top. Cover with foil. Bake at 200 degrees for 20 minutes. 5 minutes before the end of cooking, remove the foil so that the cheese browns.
Serve the chops with pickled cucumbers hot or cold.
