Combine cream cheese, shredded cheddar, garlic, chives and desired amount of siracha.
Unwrap the burgers, you will need 2 per burger.
Place about 1 T of the filling on top of one burger patty and then place the other patty directly on top. Carefully form the sides of the burger together so that they create one large patty.
Sear on a grill or stove top in a thick bottomed pan.
Season with salt and pepper.
Cook for 7 minutes on one side and then flip to the other side and cook for another 6 minutes.
This will give you a nice medium.
Add the cheese slices and let it melt for about 30 seconds.
Place on top of the bottom portion of the brioche bun, add burger patty, bacon strips and garnish with arugula.
Serve immediately and invite guests to cut it down the middle to reveal the gooey cheese.
