Heat the sesame oil in a large skillet one medium heat. Once hot add the ground beef - breaking the beef into small pieces as it cooks. When the beef is mostly cooked, ad the garlic and ginger, cook for about one minute or until fragrant. Stir in the brown sugar, soy sauce, and red pepper flakes. Bring to a simmer, cook (simmering) for about 3 minutes or until the liquid has reduced by about half. Remove from heat.

Place the corn tortillas on a flat surface. Spoon the beef into the center of each, dividing the beef between each of the tortilla shells. Top with the kimchi, onion, carrot, and cabbage. Squeeze one wedge of lime over each and sprinkle with sesame seeds. Serve and enjoy!
