Prepare the Chip-Infused Dough
Mix: Combine flour, yeast, salt, egg, pulverized chip dust, melted butter, and hot sauce in a bowl.
Knead: Gradually add warm milk. Knead for 6–7 minutes until smooth and elastic.
First Rise: Cover and let rise in a warm spot for 40 minutes until doubled in size.
Shape and Proof
Rest: Divide dough into 9–10 balls. Cover and rest for 10 minutes.
Shape: Flatten each ball and fold in half into a semi-circle.
Second Proof: Place on a parchment-lined tray, cover, and let rise for 20 minutes.
The Crust and Bake
Coat: Brush proofed buns with egg yolk and press firmly into the coarsely crushed chips.
Cook: Bake at 400°F (200°C) for 15–20 minutes (OR deep fry in neutral oil until golden brown).
Roast the Chicken Filling
Toss: In a large roasting pan, combine sliced chicken, diced vegetables, oil, pastes, and spices. Mix by hand until fully coated.
Roast: Bake at 375°F (190°C) for 30–35 minutes.
Baste: Halfway through, spoon the pan juices over the chicken to keep it juicy.
Assemble
Slice the warm chip-crusted buns.
Stuff generously with the roasted chicken and vegetable mixture. Serve immediately.
