Really great flavors and easy. I would double the sauce next time.Ingredients:
Heat 1 tbsp oil in a large skillet and add bell pepper. Cook until pepper blisters (2-4 minutes). Add 1 tbsp soy sauce. Transfer to a plate and wipe skillet clean. Place beef slices between plastic wrap and pound lightly until 1/8" thick. Season with salt/pepper. Divide bell pepper and scallions among slices. Roll tightly into bundles and secure with a toothpick. Heat 1 tbsp oil in same skillet and sear rolls until browned on all sides. Transfer to a plate and cover to keep warm. Wipe skillet clean. Add water, remaining soy sauce, vinegar and sugar to skillet. Cook over medium heat until sauce is reduced and syrupy. Serve over rice (remove toothpicks) and drizzle with sauce.
