Savory Steak and Pepper Stir Fry

This recipe is from Good Housekeeping. It is one of the quick recipes and sounds delicious. I am putting it on Food.com for safekeeping and I'll be trying it soon.

• Ready In: 35 mins
• Serves: 4

Ingredients

• 2  teaspoons  oil
• 1 1⁄2 lbs  flank steaks, thinly sliced (or use pork tenderloin)
• 1⁄8 teaspoon five-spice powder
• 1  medium  red pepper, thinly sliced
• 1  medium green pepper, thinly sliced
• 1  small onion, thinly sliced
• 2  tablespoons brown sugar
• 1  tablespoon soy sauce, or
• 1  tablespoon  teriyaki sauce (for sweeter flavor)
• 1  tablespoon cornstarch
•  cooked rice, for serving

Directions

1. In a skillet, heat oil on medium-high until hot. Sprinkle steak with five-spice powder and 1/4 tsp salt; add to skillet. Cook 3 minutes or until just browned, stirring occasionally. With a slotted spoon, transfer to a bowl.
2. If you're not fond of peppers, you can substitute a bag of frozen broccoli florets. To skillet, add peppers (florets), onion, 2 tbsp water, and a pinch of salt. Cover; cook 5 minutes, or until slightly softened, stirring occasionally.
3. In a small bowl, whisk together sugar, soy sauce, cornstarch, 3 tbsp water and 1/4 tsp pepper until smooth. Add to skillet; heat to simmering. Simmer 1 minute or until thickened. Add beef and any accumulated juices to skillet. Cook 1 minute or until beef is heated through. Serve over rice.
