Easy preparation
In almost all recipes for a slow cooker, the preparation is relatively easy and can be made even easier. Pre-prepared ingredients such as cooking sauces are readily available to speed up the process of making a delicious meal.
Work/Life balance
Slow cookers are great for helping to achieve a healthy work / life balance. The simplicity of putting prepared ingredients into one pot to cook for several hours leaves you to get on with other things whilst a healthy meal cooks without supervision.
