[Margaret Pilkington]

When using the oven cook more than one dish.
Another way to save is when cooking veggies.....bring the pot to a rolling boil and then turn off the heat and leave the pan lid on...the veggies will carry on cooking in their own heat for quite a while.......go back after say 20 minutes and test if they are cooked enough and if not turn the heat back on and repeat the process until cooked to your personal taste.
