Cut the chicken breast lengthwise into thin slices, about 0.5 cm thick. Season both sides of the chicken slices with salt, pepper, and smoked paprika, and spread mayonnaise on each side. Cover and refrigerate the chicken for 24-48 hours.
Boil some eggs and cut them into smaller pieces once they are cooked.
Wash the lettuce and break it into smaller pieces by hand. Set it aside.
Cut the cornichons into 4 pieces lengthwise.
To make the dressing, mix together all of the ingredients in a bowl.
On a serving plate, arrange the lettuce, cornichons, and eggs.
Preheat a pan over medium heat and add 3-4 tablespoons of sunflower oil.
Dip each side of the chicken slices into breadcrumbs to coat them in a thin layer.
Place the chicken in the preheated pan and cook each side until it becomes golden brown, about 5-7 minutes per side.
Cut the chicken into smaller pieces and arrange it on top of the salads. Pour the sauce over the top.
