In a bowl combine oil, garlic and 1 TBS of the Greek seasoning and mix until incorporated (you can also use a strongly flavored Greek salad dressing for this).
Oil 4-5 metal skewers.
Peel your shrimp, removing the tails and skewer 5-6 per skewer (don't "mash" them together, just allow the shrimp to touch).
Wash zucchini, cut into 1/2 inch or a little thicker rounds and skewer each zucchini so they are flat.
Pour about 1 1/2- 2 TBS of your oil mixture into a small ramekin and use that to brush your shrimp and your zucchini liberally on both sides. If you used Greek seasoning to make the mixture, shake a bit additional onto the shrimp and zucchini.
Clean & oil your grill and then heat to high. Place zucchini on first and grill for 3 minutes. Place shrimp on the grill.
Turn Zucchini over after its been on the grill 4 minutes total. Shrimp should take about 6-8 minutes total to cook (turning once halfway). Zucchini should take 7-9 minutes to cook. Cook time will depend on the size and thickness of your shrimp/zucchini), so eyeball them closely.
Toss your greens, olives, tomatoes and 3/4 cup of the feta with your remaining oil mixture/dressing 9or as much you enjoy).
With a minute to go on the grill, sprinkle 1/4 cup of Treasure Cave Feta Cheese onto your zucchini and shrimp, close the lid for 60 seconds, then remove.
Choose to place skewers as they are atop the greens or arrange them similar to what I did in the photos and enjoy!
