Simple and satisfying.

Cut beef into thin slices, or use ground beef. Cut long onion diagonally into 1-1½ inch pieces. Put shirataki into boiling water, then drain.

Mix sugar, mirin and soy sauce in saucepan and bring to boil (you can substitute sake for mirin in a pinch). Add beef. Remove after color changes. Add onion and shiritaki and cook for 3-4 minutes. Replace beef.

Serve over cooked rice in individual bowls.
