Clean meat (remove extra fat) and cut into small cubes.
Putting the meat aside, in bowl combine all other ingredients and mix.
Taste mixture and when happy add in raw meat - coating well.
Cover and let marinate for 30mins in the refrigerator.
Fire up the BBQ.
Take skewers and add meat (start at bottom and work your way to the top of the skewer).
Place souvlaki on BBQ and cook for about 5-6mins on each side (this will vary depending on what meat you are using, so cook to preference (e.g. med, well, etc.,).
Once done, remove, and serve the souvlaki some fresh tzatziki!
Notes
Feel free to add more olive oil if you feel it's not coating all the meat. Also, have a favorite herb? Make it your own. Go Crazy!
