You can use the olive oil from that can in the recipe, quite a lot. It adds a great umami, depending on what the dish is. Otherwise, open it up slightly, pour the oil into the trash and then open it the remainder of the way with a paper towel over the top. You can pull on the finger tab through the towel. That will stop most splash damage. Unless your the guy that opens milk cartons on those shoppers Network commercials. If so ... you're SOL.
