                Turn your oven on to 175°C (350°F) so it's good and hot when you need it.

                Throw your thawed potatoes, both soups, chopped onion, and half the cheese into a big bowl. Mix it all till smooth and even.

                Spray a 23 x 33 cm pan with nonstick spray, making sure the corners are covered so nothing gets glued on.

                Plop the potato mix into your pan and spread it out flat so it fills every edge.

                Sprinkle on whatever cheese you have left and drop little chunks of margarine all over so it melts in.

                Slide it into the oven and let it cook for 45 to 60 minutes. You want the top gold and a little crispy and the sides bubbling.
