For me, Cioppino with Dungeness crab, colossal shrimp, green mussels, fish like mahi-mahi or rock fish, squid.
Come to think of it, I have not had this for a while. Better do it soon while the weather is still cool to eat this heavenly chowder.

By the way, this is one of the first dishes I made when I self-taught cooking, back when I was perhaps 35. The other dish was Cajun blackened fish.
PS. I always start mine with mirepoix stewed for a couple of hours to form a thick sauce with a chicken stock and white wine, before tomato is added. The seafood is added at the end, and has to be timed just right to avoid overcooking.
