Make the kimchi slaw: Chop the kimchi. In a mixing bowl, combine the kimchi with the shredded carrots, green onions and cilantro. Set aside for about 15 minutes or place in refrigerator until ready to use.
On a stove-top grill pan or outdoor grill, grill the hot dogs over medium-high heat, rotating to get even grill marks on all sides, about 5 minutes.
Grill the buns if desired.
Make the siracha aioli: Whisk together the mayonnaise and Sriracha sauce in a small bowl. Set aside.
Place one hot dog in each bun and top with the kimchi slaw and a dollop of aioli. Top with sesame seeds and enjoy!
