Add the ingredients into a small mixing bowl then whisk to combine and set aside.
For the beef:
Heat a large skillet over medium-high heat then add the ground beef, season with pepper, and brown until the beef is cooked halfway through. Add the green onions then continue to saute until the beef is fully cooked. Drain if necessary then return to the skillet.
Pour the sauce into the skillet then stir to combine and cook until the beef has absorbed nearly all the sauce, 1-2 minutes. Turn off the heat.
Scoop cooked rice into bowls or inside fresh lettuce cups then scoop the beef mixture on top. Serve with kimchi and spicy mayonnaise if desired.
