A delightful twist on the classic ham and cheese sandwich, perfect for any occasion.
In a mixing bowl, combine the softened butter, mayonnaise, Dijon mustard, minced onion, and poppy seeds until well blended.
Ensure the butter is softened to make mixing easier and achieve a smooth consistency.
Spread the prepared mixture evenly on the cut sides of each bun.
Apply a generous layer for a rich flavor in every bite.
Layer each bottom bun half with a slice of Swiss cheese and a slice of ham.
You can double the layers for a heartier sandwich.
Place the top bun halves over the layered ingredients to close the sandwiches.
Press gently to secure the layers together.
Wrap each sandwich individually in foil.
Ensure the foil is tightly sealed to retain moisture during baking.
If freezing, place the wrapped sandwiches in the freezer. To bake, preheat the oven to 350°F (175°C).
Label the wrapped sandwiches with the date if freezing for future use.
Bake the sandwiches in their foil wraps for 1 hour if frozen, or 30 minutes if freshly made.
Check the sandwiches halfway through baking to ensure even heating.
Serve the sandwiches warm, and enjoy!
Pair with a side salad or soup for a complete meal.
