There is nothing better for a busy working client than to come home to a hot meal after working a long grueling day at the office. If you are helping your clients pick out a crock-pot, I highly recommend one with a removable crock for ease in cleaning. Your clients do not have time to hand wash things or they would not need you. I also recommend they purchase the larger size so all my wonderful food will fit nicely. Other than adding frozen food to the crock-pot, there are not many things that cannot be adapted for its use.
Most soups are perfect for leaving to cook on the low setting all day so take advantage of it.
Just ask my clients. Cooking times vary from recipe to recipe, but you can expect most things to fully cook in 6 to 8 hours. There are some food safety guidelines you should know about when using a crock-pot and a test to determine its ability to reach and maintain a safe cooking temperature. In two hours, use a thermometer to check to water temperature. It should have reached 160 F or higher during this time.
