Start by chopping the bacon, onion and chives and setting them aside.

Get your cast iron pan on the stove, add the bacon and turn on the heat to medium. This allows the bacon fat to render own and then fry the bacon.

Once the bacon is crispy add in the onions and cook till translucent.

Then add in the ground beef and season with salt and pepper. Mix well and make sure to break up the meat as you don't want big clumps.

Once the beef has turned fully gray/cooked you can add in the mustard, mayo, ketchup and cream cheese. Mix well till everything is combined.

Turn off the heat and cover the top with the shredded cheddar or mozzarella cheese and then pop it into an oven on the broiler setting to melt the cheese.

Once the cheese melts and gets a bit of colour remove from the oven

Garnish with the chopped chives and serve.
