In a deep sauté pan, add 1 TB olive oil on high heat. Coat it well. Add the chicken, skin side down and sear, about 3 minutes on each side. Remove from the pan and set aside.
To the pan, add the onion, garlic, turmeric, salt and pepper. Cook the onions until translucent. Add the chicken back to the pan, add the beans and water. Reduce heat, cover and let cook about 40 minutes until the chicken has cooked through.

Once the potatoes are in the chicken pot, in the potato pan, add the remaining oil, the herbs, spinach and fenugreek seeds. Sauté until all wilted down. Add to the chicken pot, along with the lemon juice and cook for another ten minutes. Serve with rice and/or naan.
