Just reminiscing about 70's/80's meals and remembered the 'cheese pie' I used to get at school in the 80's early 90's! have googled and lots of the recipes have onion and things in! not my school cheese pie so be off! 
Can anyone else remember it? it was definitely just cheese and egg and was crispy brown cheese on top.
And for the 'what is your unreasonableness?' just to ask for the recipe! please!
