Preheat oven to 450°F (425°F if not using convection).
In a bowl, mix ground chicken with salt, garlic powder, and onion powder. Let it sit briefly.
On a large sheet of parchment, sprinkle flour and press chicken into a very thin oval (¼–⅓ inch).
Lightly dust the top with flour, brush with egg, then coat fully with panko. Spray generously with avocado oil until crumbs look glossy with no dry spots.
Flip using parchment, repeat egg + panko on the second side, and spray again thoroughly.
Transfer to a lightly oiled sheet pan. Bake 15 minutes, then broil 4–5 minutes until deeply golden and crispy.
Remove, sprinkle with flaky salt, and rest 1–2 minutes.
Brush generously with Nashville hot sauce while hot.
Toss slaw with vinegar, olive oil, and salt. Let it sit briefly.
Slice or tear the chicken into large pieces.
Plate over slaw, add pickles, and finish with ranch, scallions, and dill.
