I need some advice on these slow cookers everybody is going on about, I'm getting home me at 7 after work and all I do is put some chicken in the oven and chop up some veg and put it in the stove it takes 2hours and it's taking the Micky now I'm not sitting down to eat my dinner until 8.30 9pm I don't believe in microwave ready meals for quickness I use to make them in a factory years ago and put me off them. So anyway my client said she leaves a small joint of beef from 8 till 6 when she gets home from work and it's ready! She just puts a few veg in a pan and it's all done in 20mins. Is it safe to leave them on all day I'm petrified incase it set on fire while I was out of the house.
