Baked Hawaiian Sandwiches

INGREDIENTS

• 24 Hawaiian bread rolls (such as King's®), split
• 12 thin slices of honey-cured deli ham, halved
• 12 slices Swiss cheese, halved
• 12 thin slices deli smoked turkey, halved
• 12 thin slices provolone cheese, halved
• ½ cup butter 
• ¼ cup white sugar
• ¼ cup dried onion flakes
• 2 tablespoons poppy seeds
• 1 tablespoon honey mustard

DIRECTIONS

1. Place a rack into lower half of the oven and preheat the oven to 400 degrees F (200 degrees C).
2. Arrange bottom halves of Hawaiian rolls on a baking sheet. Place a half slice each of ham, Swiss cheese, smoked turkey, and provolone cheese onto each roll bottom. Place top halves onto each bottom to make sandwiches.
3. Melt butter in a saucepan over low heat; stir in sugar, dried onion flakes, poppy seeds, and honey mustard until mixture is smooth and sugar has dissolved, about 2 minutes; brush over the tops of each sandwich.
4. Bake sandwiches on the preheated oven's lower rack until tops are golden brown and fillings are hot, about 15 minutes.
