I'm also trying to limit my bread. On work days I used to have 2 slices of toast in the morning, 2 slices of bread for a sandwich at lunchtime and I have no say in what we have for evening meal so could end up having pizza/ garlic bread/ something on toast etc. too. I can't cut out my pre-work toast because nothing else keeps me full for long enough, though on my days off work I won't have toast anymore. For lunch I've switched to pasta, not much better but at least a bit of variation. Ideally I'd switch to salad but I don't like salad so with the pasta I'm adding more other things (tomatoes, onion, mushroom, sweetcorn) to fill up on that and have less pasta. Can't do anything about evening meals really except have try to have less of whatever it is we are having.
I've also switched to brown bread so slightly healthier, though still on white pasta.
