Broccoli Beef

1 1/4 lb round or sirloin steak, sliced into thin strips
1/4 cup oil
2 cups water
1 med onion, cut into 1/4" slices
1 tsp garlic salt
1/2 tsp ground ginger
2 stalks broccoli, chopped
2 Tbsp cornstarch
3-4 tsp sugar
4 Tbsp soy sauce
1 med. tomato, cut into eighths

Heat oil in skillet. Add beef and cook, turning frequently, until brown. Stir in water, onion, garlic salt, and ginger. Heat to boiling and reduce heat. Add broccoli. Cover and simmer 12-15 minutes for round steak, 5-8 minutes for sirloin.

Blend cornstarch, sugar and soy sauce in small bowl; stir into beef mixture. Cover, cook over low heat stirring constantly until mixture thickens and boils. Let boil for one minute longer while stirring. Reduce heat to low; place tomatoes on beef mixture and cover. Let cook-just until tomatoes are heated through, about 3 minutes. Serve with rice.
