Slice the chicken into thin pieces. Cut the zucchini, potatoes, carrots, and parsnips into small bite size pieces. Slice the onion into half moon shapes.
Arrange the chicken and vegetables on a large sheet pan.
In a small bowl mix olive oil, lemon juice, garlic, oregano, thyme, paprika, salt, and black pepper.
Pour the marinade over the chicken and vegetables. Toss gently to coat everything evenly.
Spread everything into a single layer so the vegetables roast properly.
Bake for 30 to 40 minutes, until the chicken is cooked through and the vegetables are tender and lightly roasted.
Serve warm.

Notes
Cut the vegetables into similar size pieces so they cook evenly.
Do not overcrowd the pan. If needed, use two sheet pans so the vegetables roast instead of steam.
For extra Mediterranean flavor, top with fresh parsley or a little crumbled feta cheese before serving.
