Beef Pepper Steak (My first ex-husband still asks for this simple 20 yr old recipe... I'd do it much better now, but it was delish)

Beef Pepper Steak

2 Tbsp. Oil

1 1/2 lb. sirloin steak cubed
2 cups water
2 beef bouillon cubes
5 tbsp. soy sauce
2 green peppers cut into 1/4" chunks
1/4 cup cold water
2 tbsp. corn starch
2 cups white rice (I use minute rice)

Brown sirloin steak in oil

Add water, bouillon cubes, soy sauce and peppers, simmer until peppers are softened

Whisk cold water and corn starch together, add to simmering pan and simmer until  thickened

Serve over rice
