1/2 lb. thin sirloin tips (cut into strips)
2 tbsp. oil
1/4 c. chopped onion (I use more)
1 clove garlic
1 tsp. salt
dash pepper
1 beef bouillon cube
1 c. hot water
1 lb. can (2 cups) diced tomatoes
1 large green pepper (thin rings)
2 tbsp. cornstarch
1/4 c. cold water
2 tbsp. soy sauce

Brown meat slowly in hot oil. Add onion, garlic, salt and pepper. Dissolve bouillon cube in hot water; add to meat. Cover and simmer slowly for 30 minutes. Add tomatoes and green pepper; cook another 30 minutes (or longer). Combine remaining ingredients and stir into meat mixture. Bring to a boil and cook, stirring constantly, 5 minutes longer. Remove garlic. Serve over hot rice.
