In a large skillet over medium heat, sauté the ground beef until cooked and no longer pink, about 5-7 minutes.
Drain the fat from the skillet.
Push the ground beef to one side of the skillet and add the sesame oil to the opposite side.
Add the garlic to the hot oil and sauté until fragrant, about 2-3 minutes.
Mix the garlic oil into the ground beef.
Add the coleslaw mix.
Drizzle on the sriracha, the vinegar, and the soy sauce.
Add the sugar, the salt, and the pepper.
Sauté until the cabbage is wilted, about 5 minutes.
Sprinkle with the toasted sesame seeds and the green onions.
