I'm a child of the 80s, but we were too poor for Findus! Did get a lot of food from Iceland, though (as they would deliver, and we didn't have a car). I do remember her having the boil in the bag cod things from time to time (but not me, I hate fish).
My mother is definitely a disciple of the 'fat is bad' crusade. If something HAD to be fried she'd use a couple of sprays of Fry Light, but if she could avoid it she would. Mince for Spag Bol would be boiled for an age (stinking out the house) before everything was assembled and put in the oven. She isn't a fan of taste, either (except Marmite, which would be added to said Spag Bol, but then clash awfully with the soy sauce I liked adding on afterwards): I don't think I came across herbs and spices til I went to uni. And garlic was most definitely out of the question! She also likes her food bone dry, so roasts would be served almost dehydrated. I did get gravy, but she had to be taught (not taking it herself) that using beef granules to put over a roast chicken dinner wasn't that pleasant!
She's very keen on pudding and can't have a meal (lunch or dinner) without. Naturally, these are mainly low fat yoghurts or the like. I remember her asking me a few years back what I'd have for pudding, and was horrified when I said we didn't. The only time we do is on Sundays, after roast (and maybe Monday if there's any left over).
My style of food is completely different to hers. I've kept a fully-stocked herb and spices cupboard for many years, for a start, and switched to real oils and fats a long time ago. Plus, you can never have too much garlic! I suppose another important difference is that I enjoy cooking so can be bothered to spend time on it, it's not a chore like it is to my mother.
