PROCEDURE: CAUTION: DO NOT INCREASE THE PROPORTION OF
ONIONS, PEPPERS OR MUSHROOMS. Wash tomatoes and dip in
boiling water for 30 to 60 seconds or until skins split.
Dip in cold water and slip off skins. Remove cores and
quarter tomatoes. Boil 20 minutes, uncovered, in large
saucepan. Put through food mill or sieve. Saute onions,
garlic, celery or peppers, and mushrooms (if desired) in
vegetable oil until tender. Combine sauted vegetables and
