Mix together chicken broth or chicken stock, diced tomatoes or fresh cooked tomatoes and peanut butter. Pour over chicken. Make up a spice blend of cumin, ground coriander seed, black pepper, crushed red pepper flakes, and salt and black pepper to taste. I keep tomato paste in a container to add to stews, etc. Add the tomato paste if you have it, to add a nice pungent tomato taste.
