To the slow cooker add your cooked ground beef, bell pepper and onion.
In a mixing bowl whisk together the garlic, beef broth, worcestershire sauce, salt and pepper.
Pour the beef broth mixture over the beef.
Cover and cook on low for 3 hours.
Open the slow cooker and add the tortellini, stirring to cover it all.
Cover and cook for 30 minutes to an hour until the tortellini is cooked through.
When the tortellini is cooked though, stir in the cheese and heavy cream.
Cover and let melt for 5 minutes.
Serve!
