Heat the oil in a cast iron pan over medium high heat.
Add the ground beef and garlic. Using a meat chopper to break it up, cook until browned all the way through, about 3-5 minutes, then drain the grease.
In a medium mixing bowl, add the ingredients for the sauce and whisk together until combined.
Pour the sauce over the beef and simmer until thickened slightly.
Serve over rice with steamed veggies and garnish with green onions.
