Pat dry the chicken thighs.
5 chicken
Heat the oil in a medium size soup pot over med-low heat. When the oil is hot, add the chicken and cover the pot. Cook for 10 minutes, turning once or twice. The object is to steam the chicken not to brown it; you want to get rid of the pink color.
2 tsp vegetable oil
Stir in the leeks and cover the pot and cook until the leeks begin to soften, about 5 minutes.
1 large leek
Add the tomato paste, toss and cook for 30 seconds or so. Add the carrots, parsnips, celery and cook until the veggies begin to soften, about 5 minutes. Add the stock, water and salt and bring to a vigorous simmer over high heat. Lower the heat, maintain a gentle simmer and cook uncovered for 45 minutes. The chicken should be very tender and falling off the bone. Remove the chicken and set it aside. Allow the chicken to cool.
1 tbsp tomato paste, 2 carrot, 1 parsnip, 2 stalks celery, 4 cups chicken broth, 3 cups water
While the chicken is cooling, rinse the quinoa well in a strainer and add the quinoa and the zucchini to the broth and cook for another 20-30 minutes.
⅓ cup quinoa, 1 small zucchini
