what would YOU do? (pic)
Imagine, your the captain flying along happily, there is a small vibration engine reading indicate it as well, then a sudden bang, vibration stops, all reading normal.
then a few sec later, a member of the cabin crew call you out to look out the window, you then see this!
what would you do.

Mr Ramsden would be proud of it 
his "exploded" view drawings of just about everything that flew or was on an aircraft were an absolute work of art and the first stop when I got the mag.

Well I'll be doggonned!!
How does the engine look on your side?
OK we've got one left. That'll get us back. And I don't see any malfuntions indicated yet.
The damn thing is still working but I'll back off on its power while we slow down a bit.
Call a Pan and tell them that we need priority for a heavy landing and emergency services alerted.
Better add that the cowlings have dropped off our left engine and we don't know where they went..
The pax are probably having fits. Better give them a confidence burst. Natter natter.
This one isn't in the book so I'll just do what seems best.
Some buffet. Why didn't we notice that before.?
Better at this speed.
Hydraulics OK.
While we are up here I'll drop the gear as a precaution and try some flap.
What speeds so I need for the landing at this weight.
Routine return?
How would a pro handle it?

Ladies and Gentlemen, welcome aboard Jetstar. Looks like one of our pushback devices lost it again. But dont worry. We are just as good as Virgin Blue. Watch now as I stall the aircraft to prove it! Yee haa!

Why would you shut it down? It's only the cowl that's failed, the engine is running normally. There will be a slight increase in drag on that side which will be easily corrected with rudder and/or increased thrust on that side. Reduce to minimum speed to reduce the aerodynamic forces on the now exposed bits and make a normal two engine approach and landing. As to where that would be would depend on my position reference departure/destination/alternates.

Assuming that the cowl has gone over the back and not down the intake (logically) and the engine's vital signs are good, keep it running and reduce to minimum practicable speed. Land at the nearest suitable and don't use reverse on that side. Turn it off after rollout and have a visual check for leaks before taking it to the gate.
Take a note of the exact position of the point of cowling departure (if possible) for subsequent recovery.
If nothing hit your flaps / aft surfaces - you are not that badly off at all. Any airframe vibration might well prompt a low speed handling check at a safe altitude. That top cowling support and associated connected panels looks like a candidate for departure so a track away from built up areas - as far as possible - would be worth asking for.
Definately a PAN to get traffic, routing and landing priority - but nothing more drastic.
The PA would prove the biggest challenge.
