Wondering how you guys would get this one out. It's a 10mm bolt, recessed, and the break was jagged and not clean.

Is that a water pump? It might be easiest to just replace it, and let the rebuilder worry about extracting that broken piece from your core. Drilling out a jagged, broken, recessed bolt is near impossible in my experience.
 
Aren't the 2 other bolts enough?
Probably, but I don't like that.
As noted take the plate off. Then try and grab the reminder if the bolt with a Vise Grip.
There won't be enough as this is way below the plate.

Remove plate and see what you have to work with.

Pretty much any of the above already mentioned are workable options.

IrwinHanson, along with their competitors, extractor would take that out. Might have to use a dremel to smooth it up some before a center punch. I just don't see any problem here.
 
A lot of you are giving the false perception that it is easy to drill this out without damaging the threads. It isn't. This looks like one of the easier ones, but it is still tricky.
 
I have an easy out set a friend lent me, but I don't have bits strong enough to drill a starting hole.
 
Use a LH drill bit. Take something of the appropriate OD to someone with a lathe and have them thru-drill, say 1/8" or 3/16"

Now you have a centering jig to set in the plate and guide your pilot hole. Once you've got a start you can keep stepping up with LH bits, just don't exceed the minor dia of the threads.

Don't use an EZ Out. Ever. They're brittle and they snap and too hard to drill so then you enter wire EDM territory

The welded nut approach is also a good one.

Honestly if you just took the whole thing to a machine shop they'd probably have it out in 15 min, with most of that time spent devising a way to hold it on a mill table/in a mill vise
