Quick pickle your vegetables (optional but worth it!).

Start browning the beef.

When the beef is halfway done, add soy sauce and green onions.

While the beef cooks, combine the vinegar, honey, ginger, and red pepper flakes in a separate bowl.

Once the beef is cooked, stir in the garlic.

Pour the vinegar mixture over the beef, stirring to coat.

Remove from the heat, and stir in the sesame oil.

Serve hot with rice and desired toppings.
