I picked up 4 beautiful, funky tomatoes from the Hollywood Farmer's market this sunday and I must use them tonight before they go squishy on me.
I don't know for sure if they are heirlooms, but they to have those funky ridges and streaked or faded colors, purples to greens to reds. The farmer told me they were good stewing tomatoes.
My only concern is that I do not have enough to make a proper sauce, though they are rather large, I'd say about a pound or so total in weight. However it is just my girlfriend and I.... so we don't need that much!
