Easy Pepper Steak

This is one I got off the internet and found it to be very easy and tasted ok. I would make it again.

2 lbs. sirloin steak
1 pkg. brown gravy mix
3/4 c water
1 tbs. soy sauce
1 Tbs canola oil
1 tsp garlic powder
1/4 tsp. pepper
1 onion (sliced)
2 bell pepper cut in strips
4 c. cooked rice

Heat oil in large skillet and saute steak strips until brown. Combine brown gravy mix, water, soy sauce, garlic powder and pepper. Stir into steak mixture. Bring to a boil and simmer for 10 min. Add onion and bell pepper and simmer 10 more min. Serve over rice.
