Prepare the rice from scratch or heat up leftover rice.
Combine the brown sugar, soy sauce, 1 tablespoon sesame oil, Gochugaru and ground ginger in a bowl. Stir to combine and set aside.
Heat the remaining sesame oil in a pan over medium heat. Add the garlic and cook for 30 seconds. Add the vegan beef crumbles. Break it apart with a wooden spoon and cook for 2-3 minutes. Add the prepared sauce and cook for an additional 2-3 minutes, or until hot and bubbly. Stir in half of the green onions and turn off the heat.
To serve, split the rice between four bowls and top with the vegan beef mixture. Top with the remaining green onions and sesame seeds.
*You can sub the vegan beef crumbles for cooked lentils.
