In a bowl, whisk together the soy sauce, brown sugar, sesame oil, and gochujang sauce.
Heat oil in a cast iron pan or large pan overĀ medium-high heat.
Add the meat, onion, and garlic, breaking it into crumbles until no longer pink.
Add the sauce and let simmer until the liquid has reabsorbed, about 2-3 minutes. Add green onions and sesame seeds; and toss together.
Serve over warm rice, fried egg, and serve.
