Slice chicken breasts in half lengthwise, then cut into six thin pieces.
Marinate in pickle juice and milk for 15 minutes.
Meanwhile, prepare the pimento cheese by grating the cheddar and mixing it with mayo, pimentos, salt, and chopped jalapeños until creamy, then set it aside.
Prepare a dredging station with tapioca on one plate, whisked egg in a shallow bowl, and Cauli Crunch mixed with onion powder, paprika, garlic powder, and salt on another plate.
Remove the chicken from the marinade and coat each piece by dredging first in tapioca, then in egg, and finally in the seasoned Cauli Crunch, setting them aside on a plate.
Heat half the avocado oil in a large skillet over medium heat, cooking two chicken breasts at a time for 5-6 minutes per side until golden brown and cooked through.
Repeat with remaining oil and chicken.
Arrange the buns face up on a cookie sheet and broil for 1-2 minutes until lightly toasted, keeping a close eye on them.
To assemble, place sliced jalapeños on the bottom bun, add a crispy chicken breast, drizzle with ½ tablespoon of honey.
Top with a generous spoonful of pimento cheese, and finish with the top bun
