Solved it - had to use "key,value" - here is the revised template:
<VirtualHost *>
{% for site,value in sites.iteritems() %}
ServerName {{ site }}
{% for vhost in value.vhosts %}
ServerAlias {{ vhost }}
{% endfor %}
DocumentRoot /var/www/html/{{ site }}
<Directory /var/www/html/{{ site }}
AllowOverride All
Order allow,deny
Allow from All
</Directory>
{% endfor %}
</Virtualhost>
iteritems() is there to get around the "too many values to unpack" problem.
