When broth comes to a rolling boil, drop in the separated sliced roast beef and remove immediately from heat. Using a slotted spoon, remove roast beef from broth after 2-3 minutes. Return broth to stove on high setting and sprinkle Wondra flour over surface, stirring briskly to avoid lumps.

Simmer over medium heat 5 minutes. At the last minute, drain the sliced mushrooms and add. Pour over roast beef on white bread or buttered and toasted buns or bulkie rolls. Top with thin slices of tomato or a few lettuce leaves, if desired. Season to taste with salt and pepper.

Serve.
