The typical vegetable oil molecule is large enough to be a solid, however because of the three long arms, which get twisted around, it is difficult to make a nice crystal lattice. So vegetable oil acts like a solid that has partly melted, and is viscous because the molecules can't move around each other easily like a small molecule can.
