Just a couple of things I've not seen mentioned. Home-made fish and chips cooked in lard. Up until my teens we rarely had fish and chips from the chip shop. My mother's batter was to die for and they never tasted better than straight from the pan onto the plate. I think mid-60s there was a fad for mixed grills, the american influence - I suppose now it's called an all-day breakfast. It was always on a saturday lunchtime and the only day my father cooked. In our house it was always, bacon, eggs, black pudding, tomatoes, mushrooms and baked beans with fried bead.
I should also mention kippers and baked rolled herrings when they were cheap and plentiful.
