Stir together the tomato puree, and the Amore Tomato and Garlic Pastes.
Scatter half of the peppers and mushrooms in a large slow cooker*. Sprinkle the chicken with salt and pepper. Place it in the slow cooker. Add the remaining vegetables and pour the sauce over all. Cover and cook on low 5 to 6 hours or until the chicken is tender.
Remove the chicken from the slow cooker. Add the Amore Herb Paste to the sauce and stir well. Spoon the sauce over the chicken and serve hot.
*To cook on the stove top, place all the ingredients except the herb paste in a large pot. Cover and cook on medium heat, stirring occasionally, until the chicken is tender, about 1-1/2 hours. Add a little water if needed. Stir in the Amore Herb Paste.
