Never use those pink, crinkly tomatoes which look something like milk stained with plum juice.

If tomatoes are picked unripe, and then allowed to ripen afterwards, they become rotten and worthless.

Slice up half a dozen or more tomatoes--sometimes it will be necessary to remove the core and pips, sometimes not; add a little oil, a little vinegar, and some pepper and salt.

Tomato salad is one of the few that are very nice without any oil at all.

Of course, this is a matter of taste.
