For best results, choose a wide pot to allow dumplings to cook in a single layer. If using pre-cooked or rotisserie chicken, omit the boiling step and add the chopped chicken when the peas and milk are introduced. The soup can be refrigerated and reheated, or frozen for up to three months. For a slow cooker adaptation, sauté vegetables and roux first, then combine ingredients in the slow cooker and follow the provided timing. Gluten-free flour and bouillon may be used as needed.
