Preheat oven to 350°F while you prep ingredients
Place entire tray of Hawaiian rolls on clean surface, preserve their lattice shape when slicing
Using a large knife, carefully slice rolls horizontally in one continuous motion
Distribute cheese slices evenly on bottom halves, leaving edges clear
Cook bacon (if using) in a skillet until crispy, then crumble into the cheese pockets
Return top halves to create mini sandwiches, gently press seams to secure
Mix melted butter with garlic powder, onion powder, parsley, salt, and pepper
Generously brush butter mixture across tops, focusing on seam areas for extra flavor
Cover rolls with aluminum foil and bake 12 minutes
Remove foil, shift oven to broil, and finish with 5–7 minutes for golden crusts
Let rest 2–3 minutes before slicing and serving for clean, cohesive bites
