Cook the ground beef with the ginger and garlic in a skillet at medium-high heat until the beef is nicely crumbled and fully cooked. Drain any excess fat and place the pan back on the stove.

Mix together the soy sauce, brown sugar, and hoisin sauce in a small bowl, then add it to your ground beef mixture. Let it cook for about 2 to 3 minutes so all those tasty flavors can marry together. In another small bowl, whisk the 1/4 cup water with the 2 tablespoons of cornstarch, then pour this into your ground beef. Stir continuously until the sauce becomes nice and thick.

Sprinkle some red pepper flakes, black pepper, and green onions to taste. Serve it warm over rice or noodles of your choice. Enjoy your meal!
