Carry it all with Tern's Cargo Hold pannier set. Nifty fidlock magnetic buckles allow easy one handed operation. Capacious when needed, folds flat when not.
These bags are amazing in their capacity and the compactness when not in use - they are perfect for my weekly grocery run or getting my gymbag, lunch and computer to work and back. The only feature I would add is a simpler attachment system - I appreciate how well the velcro straps secure the bags, but they took a bit of manuevering to install. These are bags to attach and leave, not something you would take off and on easily.
