How to Make It
Heat 1 tablespoon oil in a large skillet over high. Sprinkle steak with black pepper and salt. Add steak to pan; cook 5 minutes or until browned, stirring occasionally. Remove steak from pan (do not wipe out pan).
Combine sugar, soy sauce, and vinegar in a small bowl. Add remaining 1 tablespoon oil, broccoli, and bell peppers to pan; cover, and cook 2 minutes. Uncover pan; add soy sauce mixture.
Cook 6 minutes or until vegetables are crisp-tender and liquid reduces by about half. Add steak; cook 1 minute. Divide rice evenly among 4 plates; top with beef mixture and green onions.
