This is a tough one... M y "what I do every day" answer is probably my 12", 4 qt high sided stainless steel sautee pan. It can go in the oven (hard for my wood-handled wok), handle simmering acidic things (hard for my cast iron pan), if I use enough oil it's non-stick enough (and I can deglaze with water or wine), and because it's 4 qt can also handle a decent amount of soup/curries. I even use it to boil spaghetti! That said, I don't own a ceramic sautee pan so I imagine that may be a good competitor. My SECOND pot would definitely be my Wok! Great for deep frying, stir frying, sauteeing, steaming, lots of things (but not the oven, sadly).
