DIRECTIONS

For the pickled grapes: Stir together vinegar, sugar, seeds, and pepper flakes in a small saucepan and bring to a simmer. Remove from heat and stir to dissolve sugar; let cool to warm. Stir in grapes and onion, and set aside to cool. Let stand for 1 hour, stirring occasionally.

For the beef bulgogi: Cut beef into very small bite size strips. Stir together bulgogi sauce, vinegar, and sesame oil in a medium bowl, then add beef. Let marinate for 1 hour, stirring occasionally. Heat vegetable oil in a large skillet over medium heat. Remove beef from marinade with a slotted spoon or tongs and add to skillet. Stir fry until beef is cooked through and golden brown, stirring constantly; let cool.

To serve: Place equal amounts of beef and pickled grapes into romaine leaves and sprinkle with green onions. Serve immediately, with additional bulgogi sauce, if desired.
