The reason for that is is 'at' wants to be able to mail you command
output, so it includes this:

Recommends: default-mta | mail-transport-agent

The larger than expected list of packages is, I suspect, a result of you
not having an MTA installed your system.

You can do 'apt-get install --no-install-recommends at' to avoid the
extra package, bus if you do not have working local mail delivery or an
MTA with a smarthost configured, then you may not get messaged with the
output of the jobs you run.
