My DH often has tinned plum tomatoes, seasoned with salt and pepper, on toast, Personally, I'm not keen.
Occasionally, he jazzes them up with garlic and mixed herbs. I find those much nicer, and even the DGC like them.
When our sons were young, DH often made them a simple supper on a Sunday (about the only cooking he ever did).
He mixed a tin of chopped tomatoes with a tin of chopped spaghetti in tomato sauce -both as cheap as chips - then grated cheese on top and put it in the oven until the cheese was bubbly and golden. Served with hot buttered toast, it went down a treat.
