Step 1

Warm the butter in a skillet over medium-high heat. Lightly brown the ground beef and onion.

Step 2

Stir in the bone broth, cream cheese, tomato paste, mustard, garlic powder, and salt until sauce forms. Bring to a simmer; maintain for 2 minutes until the liquid reduces slightly.

Step 3

Reduce the heat to low. Sprinkle shredded cheese evenly over the meat. Cover the skillet with a lid and continue to cook for a few minutes until cheese melts completely.

Step 4

Serve warm as is or with optional toppings and flatbread.
