Cut the chicken breast into thin quarters and marinate with lemon juice, spices, and optional Cajun seasoning.
Grill or pan-fry the chicken until golden and fully cooked, then slice thinly.
In a bowl, mix mayonnaise, ketchup, Dijon mustard, pickle juice, salt, pepper, paprika, and garlic powder until smooth.
Take the first slice of toasted bread and spread a layer of sauce. Add lettuce, tomato, and cucumber, then sprinkle a little salt over the veggies.
Place the second slice of bread on top, spread with sauce, and layer grilled chicken, cheese slices, salami, and cucumber pickles.
Finally, top with the third slice of bread, spread with sauce, and secure with toothpicks if needed.
Cut the sandwich diagonally and serve fresh with french fries or your favorite side. Enjoy! 😋
