This chicken and vegetable soup is a healthy and comforting dinner option that can be made with the help of a food processor. Pulse chicken breasts with carrots, celery, and onion until finely chopped. Cook the mixture in a large pot with chicken broth and your favorite vegetables, such as green beans, peas, and corn. Simmer until the vegetables are tender and the soup is fragrant. Serve with crusty bread for a satisfying meal.
