Put the steak in the freezer until partly frozen, then slice against the grain into 2 x 1/4 inch strips. Cook the strips in hot oil in a large skillet until browned.
Stir in tomatoes, green pepper, soy sauce, sugar, garlic salt, pepper, and ginger. Cover and simmer for 15 minutes.
Mix cornstarch into the consomme and stir into the steak mixture. Cover and simmer another 30 minutes, stirring occasionally. Serve over hot rice.
