Helena Oakum There was pasta dishes when i was growing up. Italian DM
I remember you could buy macaroni and spaghetti at the specialist deli in our town ~ run by a European immigrant family, who also sold croissants and french bread (which were shockingly exotic at the time) ~ but dried pasta wasn't carried by ordinary grocers in our area (I guess because it had to be imported). Even things like Heinz spaghetti hoops were a "special treat" because they came in a tin and were rather expensive.
This only started to change when we got a chain supermarket (it was a Sainsburys) in the next town along in the mid-80s. That's when a lot of foodstuffs that seem very ordinary now became freely available: pasta, pate, frozen pizzas, even things like fruit yoghurts.
Remember: back in the 80s, they had to put TV adverts on for Ski yoghurts to show people how, when and why you might eat them. 
And frozen chips as well. I remember when you couldn't buy them. All chips had to be deep fried in a chip pan after you'd peeled and cut the potatoes yourself and, to be honest, it was a bit of a faff and took longer than doing mash (and cost more in fat for the chip pan).
You know, I don't even remember anyone eating rice when I was a child, unless it was rice pudding (I think we got our first Indian takeaway in the mid-80s).
But those were the days when the meat van came round the estate to serve all the mothers with small children who couldn't get down to the high street easily. It really was a world of meat and two veg, with sponge and custard for afters.
I do wonder whether the start of the rise of obesity can be tracked to the rise of the chain supermarket because you needed the space of those large supermarkets in order to be able to stock frozen and convenience foods. There just wasn't space in a local grocers or small co-op to have an aisle of crisps, chocolate or biscuits or two aisles of freezers.
I go into a large big box supermarket now, and once you take out all the junk, sweets, convenience and processed food, there's not actually a lot left ~ only meat, veg, salad, staples, dairy and fish and that's only about a fifth of the store maybe? One of the big boxes near me allocates less space for fresh meat than they do for alcohol.
