TOMATO SAUCE NO. 2

Mince one-quarter of an onion, one-half a stalk of celery, a few leaves of sweet basil, and a bunch of parsley up fine. Add one-half cup of olive-oil, a pinch of salt and one of pepper, and cut eight or nine tomatoes into slices. Boil until the sauce is as thick as cream, stirring occasionally, then strain through a sieve and serve.
