Cook rice according to package directions.
Cut steak into 1/4-inch slices, against the grain.
Heat the olive oil in a large skillet over medium-high heat until hot. Add the beef and cook, stirring occasionally, for 4 minutes or until browned.
Meanwhile, combine the soy sauce, sugar, cornstarch, hoisin sauce, rice wine vinegar, sesame oil, and red pepper flakes in a small bowl or measuring cup; stir well to dissolve the cornstarch.
Add the minced garlic and minced ginger to the pan with the beef; cook for 1 minute. Add the chopped green onions and cook for an additional 30 seconds.
Stir in the soy sauce mixture and cook for 1 minute, or until the sauce is thickened and coats the beef. Serve with brown rice, steamed broccoli, and apple slices.
