In a large skillet over medium heat, cook the ground beef and onion until brown. Drain. Return to pan with salt, pepper, and broth to cover. Add some garlic powder, worchertershire sauce and paprika. Reduce heat to low and simmer, uncovered, until liquid is gone, 15 to 30 minutes.
Serve meat on buns topped with chopped onion, dill pickle slices and mustard.
