When is a beefburger not a beefburger ?

When an ingredient is left out ! Well I have just had a 'lecture' from my son. For their tea I made beefburgers, with melted cheese on top, chips and salad on the side. But apparently it did not taste nice as I had not put it in a roll ! Sigh... one day I will get this supper thing right ! It was just so funny getting told the 'ingredients' of a beefburger !
