In a large skillet, add the corn oil. Once hot, fry the ground beef, onions, ginger and garlic breaking it into crumbles until browned and no longer pink.
In a small bowl, add the sweet chili sauce and the rest of the sauce ingredients. Whisk. Pour the mixture over the ground beef and simmer for a couple of minutes. Serve over white or fried rice.
Garnish with green onions and sesame seeds if you like. I added some shredded carrots for a pop of color.
