Heat a large non-stick skillet to medium-high then add ground beef. Cook and crumble until browned then drain grease if needed.
Add zucchini, carrot, bell pepper, and about ¾ of the green onions. Sauté until vegetables start to soften, about 7-10 minutes.
Add brown sugar, soy sauce, sesame oil, Gochujang, ginger, garlic, salt, and pepper. Stir to combine, reduce heat to medium, and let cook for 5 more minutes.
Serve over rice and garnish with remaining green onions and drizzle with sriracha.
Notes
Gochujang can be found in the Asian section of most grocery stores. Don’t leave it out! It’s worth the buy and adds amazing flavor.
