   1      pound         green beans
     1/2  cup           shallots -- chopped
   1      cup           tomato -- diced

   2      tablespoons   olive oil
                        salt and freshly ground pepper

Preparation:

Remove ends from beans. Leave beans whole or cut crosswise into 1" pieces. Place beans in 1" salted water (1/2 ts salt to 1 c water). Bring to a boil and cook uncovered for 5 minutes. Cover and cook until tender, 5 to 10 minutes longer. Drain beans, turn into a warm bowl, and set aside. Cook and stir shallots, tomato and mushrooms in margarine and oil until mushroom are tender, about 4 minutes. Season with salt and pepper to taste. Add vegetable mixture to beans and toss.
