Begin by pounding the chicken breasts between two sheets of plastic wrap to an even thickness for uniform cooking.
Set up a breading station with three shallow dishes: one with flour, one with beaten eggs, and one with panko breadcrumbs mixed with paprika, salt, and pepper.
Dredge each chicken piece first in the flour, shaking off any excess, then dip in the beaten eggs, and finally coat thoroughly with the seasoned panko breadcrumbs, pressing gently to adhere.
Heat vegetable oil in a deep fryer or large pot over medium-high heat until it reaches about 350°F (175°C), or until it sizzles when a breading sample is tested.
Carefully place the breaded chicken into the hot oil using tongs, making sure not to overcrowd the pot. Fry for about 6-8 minutes, turning occasionally, until golden brown and cooked through.
Remove the fried chicken from the oil and transfer to a cooling rack set over a baking sheet to drain excess oil and maintain crispiness.
While the chicken rests, lightly toast the buns in a dry skillet or toaster for a minute until just golden.
Assemble the sandwich by placing a fried chicken fillet on the bottom half of each bun, topping with slices of pickle, then covering with the top bun.
Serve immediately, allowing the crispy chicken and tangy pickles to create a balanced bite with every chew.
