Chop up the hotdogs and vegetables, then set aside.
Line up the sauce ingredients. Make sure everything is prepared before starting to stir fry.
In high heat, put oil in the pan, and stir fry the hotdogs until it is lightly browned.
Add the onions and carrots since they take longer to cook, and stir fry for a couple of minutes.
Add the peppers and stir fry again for another two minutes.
In the pan, place the sauce ingredients then mix with the hotdog and vegetables thoroughly.
Make sure everything is coated with the sauce and the vegetables are cooked through but not yet soggy.
Plate, garnish with more sesame seeds, serve with rice, and enjoy!
