Follow these simple steps to create your Crispy Chicken Sandwich with Pickles:

1. Marinate Chicken: In a bowl, combine buttermilk and hot sauce. Add chicken breasts and marinate for at least 30 minutes (or overnight in the refrigerator for best results).
2. Prepare the Coating: In another bowl, mix together the flour, paprika, garlic powder, onion powder, salt, black pepper, and cayenne pepper.
3. Heat Oil: In a deep skillet or pan, heat enough vegetable oil to submerge the chicken over medium-high heat.
4. Coat Chicken: Remove marinated chicken from the buttermilk, allowing excess to drip off. Dredge each piece in the flour mixture until well coated.
5. Fry Chicken: Once the oil is hot (about 350°F/175°C), carefully add the chicken. Fry for 5-7 minutes on each side or until golden brown and cooked through. Use a meat thermometer to ensure an internal temperature of 165°F (75°C).
6. Drain Excess Oil: Remove fried chicken from the oil and place it on a plate lined with paper towels to absorb any excess oil.
7. Toast Buns: While chicken is resting, toast the hamburger buns in a separate skillet or oven until lightly golden.
8. Assemble the Sandwich: Spread mayonnaise (if using) on the bottom half of each bun. Place a piece of crispy chicken on top, add sliced pickles, and any additional toppings. Finish with the top half of the bun.
