VEGETABLES: (Version 1)
Here's the way I sign "vegetables." I just stick the tip of the index finger of a "V" handshape on my cheek and twist my hand twice. The "V" pivots on the tip of the index finger. The middle finger isn't touching the face.

VEGETABLES: (Fingerspelled Version)
Lots of people just spell the letters "V-E-G."
Note: If you do the twist on cheek version of the sign "vegetable" a little lower (on the side of your chin) it can be used to mean "VINEGAR." This usually isn't a problem during a conversation. I just include it here so you can impress your friends with your knowledge of a sign that isn't well known.
