In a bowl, whisk olive oil, balsamic vinegar, garlic, oregano, paprika, salt, and pepper. Add chicken slices and let marinate for 15ā20 minutes.
Preheat oven to 425°F (220°C). Toss zucchini, bell pepper, broccoli, and red onion with olive oil, thyme, salt, and pepper. Spread on a baking sheet and roast for 18ā22 minutes until tender and lightly caramelized.
Bring chicken broth to a boil. Add orzo and cook 8ā10 minutes until tender. Drain any excess liquid.
Heat a skillet over medium-high heat. Cook marinated chicken for 6ā8 minutes until browned and fully cooked.
In a small bowl, mix Greek yogurt, feta, olive oil, lemon juice, and a pinch of salt until smooth.
Divide cooked orzo between bowls. Top with roasted vegetables and balsamic chicken. Drizzle with feta yogurt sauce and sprinkle parsley over the top.
Serve warm as a hearty Mediterranean-inspired meal.
