I'm eating badly. Please inspire me with your healthy lunch ideas.

I'm a SAHM who is trying to be careful about not eating too many carbs, but often find myself scarfing down toast for lunch because I have planned everyone's meal but my own. My other fallback is soup, but there's only so much of that I can take. What do you have for lunch that is quick, delicious, healthy, and cheap? And that, preferably, your children like too?

my lunches are usually, ham/chicken/tuna salad sandwiches, tined tomatoes or beans on toast, a small jacket potato with healthy filling with loads of salad, soup (but that never fills me, rice with chicken or vegetables stirred in, stir fry with a piece of chicken chopped up and stirred in, sometimes i cook a chicken breast and just have loads of salad with it, omelet, fruit,yoghurt
