We had pasta in the 1970s (and 1960s) but my mother had lived in Italy in the 1940s. We never called it pasta though. It was either spaghetti (the long stuff others have mentioned), or macaroni, which we had in two forms - the small bits we mainly have now, which was used for macaroni cheese or as a milk pudding, and also much fatter pieces about 6 inches long.
We ate roast every Sunday, either chicken or lamb, and fish every Saturday - either plaice or dabs, usually cooked in a parsley sauce.
We ate a lot of offal: mainly liver and kidneys but heart sometimes, which none of us (children) liked, and sweetbreads. We also had rabbit (my mother used to put it in a pie and pretend it was chicken, but we always knew, because we never had chicken pie unless we'd had roast chicken the day before).
We also ate lamb quite a lot, as chops or in stew with dumplings. If we had it roast there would be leftovers minced up and used to stuff marrow. I don't think we ever had beef, except as steak and kidney pie or pudding, and the only pork I remember eating was sausages or roast gammon.
We also had things like toad in the hole and cauliflower cheese.
My father discovered curries in the 1970s and started cooking them (from scratch, not Vesta).
We had a lot of fresh fruit from the garden in season: apples, plums, rhubarb, gooseberries and raspberries, and a freezer from the early 1970s, which was packed with surplus produce and blackberries taken from local hedgerows.
