My dad didn't cook.
My mum was Cordon Bleu qualified and we ate extremely well. She was born and grew up in Germany and we lived in South London with access to a continental delicatessen in the 1960s, so we ate foods like fresh ravioli, sauerkraut and Polish sausage, chicken provencale, home made pizza, curries, spaghetti bolognese etc.
She also cooked traditional roasts, fish and chips, sausage and mash and other traditionally English food. She also made wonderful German yeast based cakes covered with streusel and home made bread.
Ready meals and microwaves weren't really a thing in the 1960s and 1970s.
