Hot Ham and Cheese with Caramelized Onions

Ingredients 

• 1 package King's Hawaiian hamburger buns
• 6 slices bacon
• 1 yellow onion 
• 8 Tablespoons salted butter, divided 
• 2 teaspoons dijon mustard
• 1 teaspoon Worcestershire sauce
• 1 pound sliced deli ham
• 1 pound sliced swiss cheese

Preheat the oven to 350 degrees F. 

Fry the bacon until crispy. Place on paper towels to drain.

Slice onion into thin strips.

Melt 1 Tablespoon butter in a small skillet; add onions and cook over very low heat for 30 minutes, stirring occasionally. The onions should turn a deep golden color and taste sweet.

Melt the remaining butter and whisk with the mustard and Worcestershire sauce. Brush each bun with butter mixture on both sides.

Top with ham, onions, bacon, and cheese. Brush the top of the bun with butter on both sides, place on the sandwich. Repeat with remaining sandwiches. 

Cover your baking dish with aluminum foil. Bake for 20 minutes or until warmed through and cheese is melted. 

Enjoy!
