On a work day I don't eat before I leave home but often will pick something up on the way to the office eg. a cream cheese bagel, smoked salmon and scrambled egg baguette or sometimes a pastry preferably with a fresh orange juice and a cup of tea.
Lunch is sandwich, crisps and water or occasionally sushi or a jacket potato with coleslaw.
Dinner varies - spag bol, chilli, jacket potatoes, cottage pie, pasta, pizza, wraps, chicken or salmon baked in the oven. Most midweek meals are served with lots of salad. After dinner I will have a yoghurt and fruit.
When at home, breakfast will be a bowl of Special K, porridge or two slices of toast (with butter, dairylea or marmite).
Lunch is usually homemade veg soup (carrot /parsnip /cauliflower /broccoli), tinned mackerel and salad or sometimes a toasted sandwich.
Dinner will be the same as above (apart from nights when we eat out or grab a takeaway). I don't keep a stock of biscuits / crisps etc (although I guess this will change as our DC grow up) so most snack options are healthy unless we can be bothered to go out and get something. I tend to keep come packets of microwave popcorn as a treat.
