Usually leftover dinner, so the same sort of food, curry, chilli, risotto, dhal, today I had Thai basil rice with pork and peppers.
If we don't have leftovers, mainly soup, noodles, omelette, egg on toast, or falafel, hummus, pitta, bit of salad etc.
All have lots of veg in and not massive portions, I tend to eat little and often, so eat better this way, more veg, less bread for a start. 'Normal' lunch of sandwich and crisps or cake, is probably not great, if you're trying to eat well.
