It has been awhile since I had this but as I recall
the squid was lightly coated with a seasoned flour/cornstarch mixture perhaps.  A very light coating.  I believe the seasonings would have been perhaps, garlic powder/salt, ground cumin, a little ground oregano (but that might just be me, since I have trouble making anything Mexican that I don't use both herbs), and a little cayenne or black pepper.  It was the combination of all the flavors.  I loved the calimari with the garlic aoli.  I was looking forward to beef barley soup tonight, thanks Julie!  lol.
