Make this Mediterranean chicken for dinner and save the leftovers because it's even better the next day! I love this meal - full of fresh flavors and good-for-you veggies and chicken. It's satisfying but light.
Heat 1 tablespoon olive oil and 1 tablespoon of butter in a cast iron or other oven-safe skillet on high heat.
In a large bowl, add chicken thighs, tomatoes, onion, and sliced peppers. Toss with seasonings, balsamic vinegar, lemon juice, and remaining 3 tablespoons of olive oil.
Add to the heated skillet, making sure chicken is spread out in a single layer.
Place pan in oven and bake for 30-35 minutes or until vegetables are tender and the chicken reaches 165°F internally.
Top with crumbled feta, chopped parsley, and optionally sliced kalamata olives. Serve and enjoy!
