Sauté the Chicken:

• Heat butter and olive oil in a skillet over medium heat.
• Add the diced chicken along with cayenne powder, red bell pepper powder, onion powder, garlic powder, chicken seasoning, and dried parsley.
• Cook for 4-5 minutes until the chicken starts to brown.

Create the Sauce:

• Stir in the sweet soy sauce, sambal, soy sauce, and heavy cream.
• Increase the heat to high and let the sauce thicken slightly, stirring continuously.

Melt the Cheese:

• Remove the pan from the heat and mix in the grated cheese until well incorporated.

Caramelize the Onions:

• In the same skillet, add the chopped yellow onions and cook over medium heat for 5-7 minutes until they become golden and caramelized.

Assemble the Rolls:

• Slice the white sandwich rolls in half and remove some of the interior to create space.
• Layer a bit of grated cheese on the bottom, then spoon on the cheesy chicken mixture.

Top and Bake:

• Combine the caramelized onions with any remaining grated cheese and fresh parsley.
• Spoon this topping over the filled rolls.
• Place the rolls in a preheated oven at 200°C (390°F) and bake for 5-7 minutes until the cheese is melted and bubbly.
