Instructions

Step 1: In a large bowl, combine 1/4 cup freshly squeezed lemon juice, 3 tbsp olive oil, 3 minced garlic cloves, 2 tsp dried oregano, 1 tsp salt, and 1/2 tsp black pepper. Add 1.5 lbs cut chicken thighs and toss to coat. Cover and marinate in the refrigerator for at least 2 hours.

Step 3: Meanwhile, prepare the tzatziki sauce by combining 1 cup Greek yogurt, 1/2 grated and drained cucumber, 1 tbsp chopped fresh dill, and 1 tsp lemon zest in a bowl. Mix well and refrigerate until ready to serve.
Step 4: Once chicken is done, serve warm with a generous dollop of tzatziki sauce on the side and optional warm pita bread.
