How to switch a Bluetooth module with a P-Channel MOSFET high-side switch?

I am looking for a high side switch to turn a Bluetooth module off when not in use.
The module uses 100mA at most and runs on 3.3V.
I am using a ATMega328 to talk to the module and it runs at 5V.

How can I use a P-MOSFET in a high-side switch circuit to switch these low current levels using 5V logic?

Lacking the ability to add an answer:

Would this work, perhaps?
