I bought pork shoulder loin. Not pork tender loin because the butcher said it would be too tender for the skewers. I cut it up into roughly 1 inch cubes & marinated it in the following ingredients:
*extra virgin olive oil (don't be afraid to over-do it on this) *lemon juice (ditto) *oregano *season salt *(or you can use salt/pepper) *garlic (I used finely minced) *onion (chopped up pieces) (oh yes, we might as well ALL stink!)
I covered it & placed it in the fridge overnite. The smell was INCREDIBLE! The next morning, I skewered it using 12" skewers. I grilled them outside til they were done, but not OVER-DONE because they dry out. This pork was so tender & the marinade just made it that much more tender. The juices were running out of the pork pieces.
I had some pita bread & slathered on the tzatziki & then plopped off the souvlaki off of the skewers. Voila!
