Step 1

Place hot dogs in a large stockpot. Cover with water and bring to a boil. Turn heat off, cover, and let sit.

Step 2

Heat a skillet over medium-high heat, add ground beef and half of the diced onions. Cook and stir until beef is no longer pink; making sure to break into fine pieces, about 8 minutes.

Step 3

Meanwhile, whisk water, ketchup, tomato paste, vinegar, Worcestershire sauce, and chili powder until smooth.

Step 4

Drain ground beef mixture and return to the skillet. Stir in reserved ketchup mixture, reduce heat, and simmer for 10 minutes.

Step 5

Place hot dogs in buns. Top hot dogs with beef mixture. Divide remaining onions on top of the beef mixture and garnish with mustard.
