Green Pea Soup, all ready to go just add hot water!!! This soup is a customer favorite. Try making it thin and putting it in a to-go coffee cup for a warm and tasty lunch. For a heartier green pea soup... boil carrots, celery, onions or other favorite vegetables in water with or without meat (ham, chicken, turkey) and add soup flakes when the vegetables are soft. You'll have a hearty meal in less than 20 minutes!
