Pete's Sauerkraut

Combine sauerkraut with its juices, ketchup, mustard, onion, sugar, salt, chili powder, and pepper in a saucepan.

Bring to a lively simmer over medium-high heat, stirring often.

Cook 2 minutes to wake up the onion and spices.

Reduce heat to medium and continue simmering about 7 minutes, stirring so the sauce does not scorch.

Serve warm when the kraut is glossy, slightly thickened, and tinted red from the sauce.
