Crumble blue cheese into small mixing bowl. Add next six ingredients and mix well. Spoon small amount of filling in to prepared tomatoes, mushrooms and celery.
To Hollow out Cherry Tomatoes:
Remove any stems. Cut a thin slice off bottom of each tomato (not stem end). Scoop out centers with the small end of a melon-bailer or iced tea spoon. Tomato cups will now sit upright on stem end.
Yield: About 1-1/3 cups filling
