In a medium glass bowl whisk oil, minced garlic, lemon juice, oregano, paprika, Greek yogurt and sea salt and pepper.
Add chicken pieces, and combine well to completely coat the chicken, cover and marinate for a minimum 30 minutes, to 4 hours, refrigerated.
Once marinated, allow chicken to sit room temp for about 10 minutes, then:
Heat a large skillet over medium-high heat and cook chicken for about 7-8 minutes, stirring until cooked through.
Meanwhile, make the Tzatziki sauce by whisking all ingredients in a small bowl very well; cover set aside in the refrigerator until ready to use.
Divide cooked quinoa equally between 4 glass meal prep containers, 1/2 cup in each.
Add in equally to each bowl as shown in my photos: chopped veggies, olives, chicken and cubed feta cheese and a spoonful of Tzatziki sauce.
Keep refrigerated for 3-5 days in airtight container.
This is perfect for serving cold! Enjoy!
