In summer we ate a lot of salads (salad being lettuce, cucumber, tomato, grated carrot) with left over chicken, or left over ham, or left over lamb - there never seemed to be much meat. Or salad with tinned sardines. Or salad with cottage cheese and pineapple (tinned). Or salad with tinned peaches and grated cheese.
The lettuce, tomato and carrot were probably from the garden. There would be a glut, so it was eaten every day.
Sometimes 'Russian salad' if there was left over cooked veg - carrots, peas, potato - in salad dressing.
Dad wouldn't eat anything spicy. He'd had curry when he was on National Service and vowed never to eat it again (to be fair they probably did add spices to cover up the taste of rancid food). So no mustard, no chilli, no herbs, no curry powder, no paprika....
We would have kedgeree which was smoked rice, fish, boiled egg - then everyone added their own amount of Sharwoods mild curry powder (came in the blue tin). My mum had a secret store of things that she added to food and never told Dad about.
My two most hated things were fish in a mushroom béchamel sauce served on rice (think grey, slimy, and a bit fishy) or egg mornay - boiled eggs, halved and flat side down, with cheese sauce on top (probably not much cheese in the sauce) cooked in the oven.
On the bright side, there was Angel Delight!
