How to create kebabs that taste Greek
The primary flavors of Greek meats are lemon, oregano, and olive oil. Typically either (or both) thyme and mint are present as well. I'd start with the following base for a marinade:


1/2 cup olive oil
1/4 cup lemon juice (2-ish lemons)
2 Tbsp oregano
1.5 tsp thyme
1.5 tsp mint


I'd also suggest adding some garlic and onion to this. Maybe 1/2 an onion and 4 cloves of garlic. Adding a 1/4 to 1/2 cup of red wine could add some depth as well (I'm assuming lamb or steak, use white for pork or chicken).

A good soak in this overnight, perhaps with some tweaks, should equate to Greek kebabs.

Other herbs &amp; spices common in Greek cuisine include: marjoram, paprika (sweet &amp; hot), and pepper. You can also find, in small quantities:  cinnamon, nutmeg, cumin, anise, coriander, fennel, and allspice.
