In a skillet, brown the ground beef until it’s cooked thoroughly. Drain and pat dry. Turn the heat down to low and add the beef back to the skillet.
In a small bowl, whisk together both soy sauces, ginger, garlic, and brown sugar. Mix in 2 tablespoons of cornstarch and continue whisking until the sauce is completely mixed. (This can be done while the ground beef is cooking, just be sure to stir it once in a while as you’re waiting for the beef to get done).
Stir the soy sauce mixture into the cooked ground beef and mix well.
Add the mung bean sprouts and cook for about 3 minutes. Add the diced onions and shredded carrots.
Remove from heat and cover with a lid. This will allow the onions and carrots to soften. Let it sit for about three minutes.
