I have been experimenting with a slow cooker recently. I put the ingredients in the slow cooker in the morning and cook them on a low setting throughout the day. It can be tiresome preparing the ingredients in the morning but it's great to get home from work and the evening meal is cooked and ready to eat. Slow cookers are excellent for cooking cheaper cuts of meat, making them really tender. They also save energy, using just one pot, rather than the hob, oven, grill etc, and save on dishes too.
