I find soups, salads (with plenty protein), stir fries and veg curries really good for getting 5 a day.
When I am trying to be healthy I often have:
saluted coarsely chopped onion, pepper and any other veg (muhrooms) and a tin of tomatoes, simmered with chilli and paprika until it makes a coarse spicy sauce and then add an egg, bung the lid on until cooked
Thai and vietnamese salads. So beanthread noodles (from amazon), any crunchy veg (cabbage, carrots, peppers, celery etc), shredded chicken or prawns, some herbs (coriander, thai basil or mint) and some dressing (eg lime, fish sauce, sugar and sesame oil, or a peanut butter / sesame oil based dressing- see asian slaw on smitten kitchen)
Curry with a bought sauce and then just shove a load of veg in like aubergines, cauliflower etc
Asian broth soups. So for example hot and sour (chilli bean paste, sugar, soy sauce, vinegar) and noodles and shredded meat or a hard boiled egg and a load of shredded veg and pak choi. Or a ramen type one like wagamamas.
