A delightful twist on the classic ham and cheese sandwich, baked to perfection with a flavorful buttery spread.
Melt the butter in a small saucepan over low heat.
Use low heat to prevent the butter from browning.
Stir in the mustard, minced onion, and poppy seeds into the melted butter. Cook gently until the onion softens.
Stir continuously to ensure even cooking and prevent sticking.
Spread the prepared buttery mixture on both sides of each sandwich roll.
Apply generously for a rich flavor.
Layer the ham and cheese slices inside each roll.
Ensure the cheese is placed between the ham slices for even melting.
Wrap each sandwich in aluminum foil and place on a baking sheet.
Seal the foil tightly to retain moisture during baking.
Bake the sandwiches in a preheated oven at 375°F (190°C) for 15-20 minutes.
Check after 15 minutes to avoid overbaking.
Serve the sandwiches warm and enjoy.
Pair with a side of fresh salad or soup for a complete meal.
