In a large pot, cook the chopped bacon over medium heat until crispy. Remove and set aside, leaving the drippings in the pot.

Add the ground beef to the pot and cook until browned. Drain excess fat if necessary.

Stir in the diced onion and minced garlic, cooking until the onion is translucent.

Add the riced cauliflower, beef broth, Worcestershire sauce, and mustard. Bring to a simmer.

Reduce heat and stir in the heavy cream and cheddar cheese until melted and smooth.

Season with salt and pepper to taste. Stir in the cooked bacon before serving.
