just an fyi, there are no such things as seedless tomatoes.
there are some new hybrids that have relatively few seeds, but are not completely seedless.
i cut and squeeze out the seeds and mucilage much like andy described, but i don't get too crazy trying to remove every single bit. a coupla seeds won't be noticed in most dishes.
