Parmesan Buffalo Burgers with Balsamic Ketchup

Added 1tbs fish sauce.to meat mixture.   Rather than arugula, topped with some basil leaves & spring mix.  Added some good balsamic to ketchup instead of making from scratch.  Served two burgers on potato burger puns & two on small sourdough rolls.  Good burgers 

We enjoy bison/buffalo meat. Skipped making the balsamic ketchup and instead sauteed the red onion until just starting to brown then added some balsamic vinegar to that and simmered until reduced/absorbed by red onion. Great way to add the balsamic flavor in less time. Used my regular favorite ketchup.

These were tasty but not particularly extraordinary. I was a bit disappointed in the balsamic ketchup - it took a long time to make and then it just tasted like really thick pasta sauce to me.
