Last time I grew them, I thought white tomatoes were kind of bland. But I did get seeds for a couple more varieties that are supposed to be flavorful. The bland ones will do better cooked in any case.
In addition to Fish, I'm planning on planting other peppers that are white when immature -- white bell peppers and Hungarian peppers.
I'm also going to try some white eggplants.
... Probably daikon and white turnips, too, though white cabbage butterflies may become a problem.
I was also looking for other possibilities, and came across "white celery"

Rediscover Fenland CeleryWinter white Fenland celery is grown using traditional celery growing methods in the rich peaty soil of the Fens. The celery is available from October to December (great British climate permitting!)
I decided to experiment by hilling up my two celery plants in the Kitchen Garden with compost-enriched soil:Fenland celery is grown in wide rows with deep trenches. This allows the soil to be banked up around the celery as it grows. This ‘earthing up’ process keeps the celery warm and protected from frost as it battles to grow through the winter months. Covering up the celery with soil also blanches it giving the sticks a paler colour and is why it has become known as ‘white’ celery.
...not sure if I believe that or not 
-- all TPS I've ever grown only made tiny tubers first season....
