Tonight we had gyros!!! I used whole wheat pitas, chicken souvlaki, sauteed onions, lettuce, and home-made tzatziki. It was yummy!!! I think I'll use the tzatziki for a veggie dip later.

I didn't feel like firing up the grill, so I broiled the chicken in the oven.
Chicken Souvlaki
(Makes 4-6 servings, recipe created by Kalyn.)
4-6 boneless, skinless chicken breasts
Marinade:
1/2 cup olive oil
1/2 cup fresh squeezed lemon juice
1 tbsp red wine vinegar
1 tbsp finely minced garlic (or garlic puree from a jar)
1 tbsp dried oregano (use Greek or Turkish oregano)
1 tsp dried thyme
Trim all visible fat and tendons from chicken breasts, then cut each bread into about 6 crosswise strips. (I made the strips about 1 inch thick.) Put chicken strips into large Ziploc bag or plastic container with a tight-fitting lid.
Combine olive oil, lemon juice, vinegar, garlic, oregano, and thyme and stir together with a whisk or spoon. Pour marinade into Ziploc bag or plastic container, seal, and squeeze bag or turn container over and shake gently so all pieces of meat are well-coated with marinade. Put into refrigerator and marinate 8 hours or more.
To get ready to grill, remove chicken from refrigerator and let it come to room temperature, then drain chicken pieces and thread onto skewers. I put six pieces on each skewer, and folded over each piece of chicken so it wouldn't spin around on the skewers. Spray grill with non-stick spray or mist with olive oil, then preheat gas or charcoal barbecue grill to medium high. (You can only hold your hand there for a few seconds at that heat.)
Grill skewers about 12-15 minutes, turning often. Souvlaki is done when the chicken is slightly browned and firm, but not hard to the touch.

Tzatziki (Greek Yogurt and Cucumber Sauce)
(Makes about 3 1/2 cups. You can cut the recipe in half, but it's so good, you really shouldn't. Recipe courtesy of Georgette.)
3 cups Greek Yogurt (or regular plain yogurt, strained as described above)
Juice of one lemon (about 3 tbsp)
1 garlic clove, chopped
2 medium cucumbers, seeded and diced
About 1 tbsp kosher salt for salting cucumbers
1 tbsp finely chopped fresh dill (can substitute mint leaves for a slightly different version)
Kosher salt and fresh ground black pepper to taste
If you don't have Greek yogurt, strain plain yogurt using a mesh strainer sitting over a bowl. If you don't have a mesh strainer, use 2 coffee filters and sit it inside a collander over a bowl. Peel cucumbers, then cut in half lengthwise and take a small spoon and scrape out seeds. Discard seeds. (If you use the small seedless or European cucumbers with few seeds, you can skip this step.) Slice cucumbers, then put in a colander, sprinkle on 1 T salt, and let stand for 30 minutes to draw out water. Drain well and wipe dry with paper towel.
In food processor with steel blade, add cucumbers, garlic, lemon juice, dill, and a few grinds of black pepper. Process until well blended, then stir this mixture into the yogurt. Taste before adding any extra salt, then salt if needed. Place in refrigerator for at least two hours before serving so flavors can blend. (This resting time is very important.)
This will keep for a few days or more in the refrigerator, but you will need to drain off any water and stir each time you use it.
