Cook Rice
Heat a large deep nonstick skillet over high heat and add the ground beef. Cook, breaking the meat up with a wooden spoon until cooked through, about 5 minutes.
Add the onion, garlic, ginger, broccoli, and bell pepper: cook 1 minute.
Pour the sauce over the beef, cover and simmer on low heat 10 minutes.
To assemble the bowls, place ¾ cup rice in each bowl, top with beef mixture, Gochujong, sesame seeds and scallions.
