Brown the beef and diced onion in a large deep skillet over medium-high heat, about 7 minutes; drain the fat.
Add broth, tomato sauce, ketchup, mustard, and the dry pasta. Bring to a boil, cover, and simmer 11-13 minutes, stirring now and then, until the pasta is tender.
Stir in the milk and cheddar until melty and creamy. Season with salt and pepper.
Serve topped with chopped pickles for the grown-ups; leave them off for picky kids.
