Place chicken breasts into a sealable bag and pound the chicken breasts to about 1/2 inch thickness. Then cut the chicken breasts in half to make 4 sandwiches.
Add milk and eggs to a bowl and place the chicken breasts into the milk mixture and allow to sit for 30 minutes.
Mix the breadcrumbs, flour, and remaining seasonings on a dish. Remove the chicken breasts and coat them completely in the flour mixture.
Heat the oil on medium high heat.
Place the chicken breasts into the heated oil and fry them for 5-7 minutes or until fully cooked and golden brown on the outside.
Serve on brioche buns with lettuce and pickle slices.
Notes
Soak the chicken breasts in pickle juice and then soak in the milk and egg mixture up to a day before making.
Store any leftovers in an airtight container in the refrigerator for up to 3 days.
Leave out the pickle juice if you don't like the flavor! The longer you soak the chicken in the juice, the stronger the flavor will be. Consider soaking it for a smaller amount of time if you like the flavor but want to decrease the amount.
