Here you go, this is real easy & you can add extra pieces. Best bit is you don't have to worry about pastry.

4 ozs chopped bacon
4 ozs grated cheese
250ml cream
1/2 C SR Flour
1 1/2 C Water
4 eggs
1 Chopped onion
Salt & Pepper

Mix all the ingredients together & put into pie dish. Cook @ 180 for 40 mins. Easy

I often add chopped tomato, mixed herbs & capsicum. You could substitute the bacon for ham no worries & add some chopped mushrooms too.
