what do you mean by virtual interface? like a vlan interface on a trunk for instance? HSRP?

By default all ASA 5555-X interfaces are routed (assuming the overall firewall mode is routed - the most common mode by far).
So, for a given interface, you just assign a nameif and an IP address in config-if command mode.

The configuration guides are always a good place to start. Here are the ones for both the cli and the GUI (ASDM):

so if your range is for instance 10.100.0../24 and you want to add a 'virtual ip" say 10.100.0.10. then you will need to add a NAT 10.100.0.10 to whatever on your Firewall. it that simple

Please see the second link in my earlier reply. It takes you straight to the ASDM interface configuration section.
