In the sign for "sandwich" your dominant hand is flat and represents some kind of meat or "sandwich filling." Your non-dominant hand is bent at the large knuckles and the thumb is extended forward (pointing in the same direction as the fingers). The non-dominant hand represents a couple of slices of bread and looks as if it is holding a sandwich. Place the meat between the two slices of bread (put your dominant hand between the thumb and fingers of your non-dominant hand) and bring the "sandwich" up to your mouth.
SANDWICH:
Note: Another way to do the above version is to place the meat into the bread twice without bringing it up to the mouth.
SANDWICH (version)
There is yet another way to sign "sandwich" that places both flat hands together (palms touching) and aims them at the mouth. It is a bit awkward but I consider it to be a good version for talking about a "hoagie" or "submarine" type sandwich.
