Chicken Souvlakia with Tzatziki Sauce

Recipe from Lorilyn Glenn

1 ½ lbs. chicken breast
¼ C olive oil
2 Tbsp lemon juice (fresh is best)
2 cloves of garlic, minced
½ tsp salt
1 tsp oregano
pepper, to taste

Tzatziki sauce:
1 (6 oz.) container of plain, Greek style yogurt
Half cucumber, peeled, seeded, and grated
1 clove of garlic, minced
1 Tbsp olive oil
2 tsp white vinegar
½ tsp salt

1. Tzatziki sauce: Combine ingredients in a bowl.  Refrigerate until ready to serve.  The longer it refrigerates, the stronger the flavors.
2. Cut chicken breasts into chunks.  In a large zip lock bag combine marinade ingredients. Add chicken and refrigerate 1-2 hours.  
3. Preheat grill. Thread chicken onto skewers (soak wooden ones 30 minutes prior). Discard marinade. Grill kabobs on med-high heat for 8-9 minutes per side or until juices run clear.
