Combine yogurt, olive oil, oregano, vinegar, whole garlic cloves, and lemon juice in a medium bowl. Add at least 1/4 teaspoon kosher salt and a pinch of black pepper. Whisk well to combine.
3 Tablespoons plain Greek yogurt, 2 Tablespoons extra-virgin olive oil, 1 Tablespoon dried oregano, 2 teaspoons red wine vinegar, 4 cloves garlic, juice of 1 lemon, kosher salt and black pepper
Add chicken to the bowl and turn to evenly coat with the marinade. Cover, place in the fridge, and marinate for at least 30 minutes. Three hours or longer is an ideal marinating time, but don't leave it longer than overnight.
4-6 boneless, skinless chicken thighs
When ready to cook, remove chicken from the fridge and preheat the oven to 425°F.
Slice the zucchini into 1” coins, then chop into halves or quarters. Chop both the onion and pepper into bite-sized chunks. Toss all these veggies together onto a large rimmed baking sheet. Line with parchment paper for easy clean-up.
1 or 2 zucchini, 1/2 medium red onion, 1 or 2 bell peppers
Drizzle the veggies lightly with olive oil, and sprinkle generously with salt and pepper. Toss to combine.
Remove chicken from the bowl and nestle each piece into a spot on the sheet pan, surrounded by veggies. Discard the marinade.
Place pan in the oven for 10-15 minutes while you prep the tomatoes, olives, feta, and anything else you’d like to serve.
1 cup cherry tomatoes, 1/2 cup Kalamata olives, 2-3 Tablespoons crumbled feta
After the chicken has been in for at least 10 minutes, remove the pan and add cherry tomatoes in among the veggies.
Roast for 5-10 minutes more, until all the veggies are tender and the chicken is cooked through (165°F on an instant read thermometer).
Remove from the oven, then add olives, feta, and parsley as you like—either scattered over the sheet pan, or added directly to individual plates to taste.
parsley
Serve chicken and veggies with extra herbs and over rice, couscous, or with pita, as desired. Enjoy!
