Make Dutch crunch bread. Combine warm milk with sugar and active dry yeast. Let sit for 5 minutes.
Combine yeast mixture with flour, melted butter, and salt in the bowl of a stand mixer. Mix together until a dough forms. Knead dough for 7-8 minutes or until smooth. Lightly grease a bowl and transfer dough to bowl, turning to coat. Cover and let rise in a warm area for 1 hour or until doubled in size.
Divide dough into 6 equal portions. Shape each portion into an oblong shape and place on a lined baking sheet. Loosely cover and let rise in a warm place for 30 minutes.
Meanwhile, make the topping. Stir together active dry yeast with sugar, oil, salt, warm water, and rice flour in a medium bowl until well combined. Let sit for 20 minutes.
Preheat oven to 400 degrees F. Place a hotel pan filled ⅓ full with boiling water in the oven.
Gently brush a generous amount of bread topping on rolls. Use all of the topping mixture. Wipe off excess topping that drips to the sheet pan. Let sit uncovered for 20 minutes.
Bake bread rolls for 15-20 minutes or until golden brown. Remove from oven and let cool completely.
Prepare chicken. Blend together marinade ingredients including olive oil, garlic, lemon juice, oregano, cumin, coriander, salt, and pepper until smooth. Pour marinade over chicken, turning to coat. Let sit for at least one hour or up to 4 hours.
Meanwhile, make godfather sauce. Whisk together mayonnaise with garlic powder, paprika, cayenne, dried basil, and oregano until well combined. Set aside.
Make honey mustard. Whisk together dijon mustard with honey, olive oil, and lemon juice until well combined. Set aside.
Heat large saute pan over medium heat. Cook chicken until golden brown and the juices run clear. Place sliced pepper jack cheese on top and cover the pan. Reduce heat to low and continue to cook until cheese is melted, about 2 minutes.
Slice bread in half and toast. Spread godfather sauce on bottom bun and top with chicken. Stack tomato slices on top followed by sliced red onion, jalapeno, pepperoncini, and lettuce. Spread honey mustard on top bun and place on top. Serve immediately.
