Cut each chicken breast in half and pound them to 1/2 inch thickness. Sprinkle each piece on both sides with paprika, salt, and pepper to your liking. Place them in a large zip lock bag or plastic bag, like a Tesco shopping bag, and pour the pickle juice over them. Press out the extra air by twisting the bag, then place that in a bowl and place the fridge for 6 hours our anytime up to overnight.

Preheat your oven to 230 C and place a wire rack on a baking sheet and set aside. While the oven is heating, stir together the flour, spices, sugar, and baking soda in a bowl and set aside. In another bowl whisk together the egg and milk. Take the chicken out of the fridge, dip each piece in the egg mixture, then coat well with the flour mixture making sure the entire piece is coated with flour.

Place the chicken on the wire rack and generously spray each piece with olive oil, coating the flour completely. Turn the pieces over and spray the other side with olive oil. Bake for 12 minutes, then turn the chicken over and bake another 15 minutes or until the chicken is golden brown, crispy, and cooked through. Remove from the oven and top with cheese of your choice and let these rest for 5 minutes.

Butter each bun and place on a sheet and bake for 3-4 minutes until toasted. Place 3-4 pickle slices on each bottom bun, top with a piece of chicken and the other toasted bun. Serve.
