In a large skillet, heat the vegetable oil over medium heat. Add the ground beef and cook until browned, breaking it apart with a spatula, about 5-7 minutes. Drain excess fat if necessary.

Add the minced garlic and ginger to the skillet, cooking for an additional 1-2 minutes until fragrant.

In a small bowl, whisk together the soy sauce, brown sugar, sesame oil, and red pepper flakes. Pour this mixture over the cooked beef, stirring to combine. Let it simmer for 3-5 minutes, allowing the flavors to meld.

While the beef is simmering, prepare the rice according to package instructions if not already cooked.

To assemble the bowls, place a serving of rice in each bowl. Top with the savory ground beef mixture.

Garnish with chopped green onions, shredded carrots, sliced cucumbers, and a sprinkle of sesame seeds. Serve warm.
