I agree that with Lucy that some suitable cook books would be a big help. The sort of things I like to do for the boys (and that they like to eat) are pasta bolognaise (you can put in any or all of tomatoes, capsicums, zucchini, mushrooms, finely sliced carrots, onion etc), zucchini slice / quiche / (you can put in zucchini, carrot, onion, corn, and/or peas), vegie bake is a good suggestion, also noodle/stir fry dishes are great, mild curry (small bits of meat and cook for ages so they are tender, tomato, potato, beans, pumpkin, brocolli, cauliflower, capsicum etc), spanish omelette as a quick option, tuna or salmon patties and you can add corn if you like (and serve with a salad) and casseroles are great. I'm sure I've missed heaps of things, but hopefully that gives you some ideas. I find the idea is to start with a simple recipe and just add to it. After a while it becomes much easier to ad lib. Good luck!
