Preheat the oven to 200°C.
Place the chicken on a baking tray and drizzle with 2 Tbsp oil and half of the lemon juice, then season with the oregano, salt and pepper. Bake for 35-40 minutes until golden brown.
When the chicken is almost done, wash the spinach and drain. Cut the feta into small cubes.
Heat the remaining oil in a frying pan and cook the garlic and caraway seeds for a few seconds, then added to the spinach and sauté for 2-3 minutes. Add the reaming lemon juice and the diced feta. Season with salt & pepper, mix gently.
Serve the chicken on top of the spinach & feta mixture.
