I'm quite fussy with my veggies,
I can't eat them steamed with salt and pepper, nor do I like them boiled. I like them sauteed or in the oven.
My favourite way to eat roast vegetables is getting some...
Parsnips
carrots
potatos (you can leave these out)
onions cut in quarters (they can go in a bit later)
I then put some olive oil in the tray, and then i sprinkle:
salt,
mixed herbs
dried chili seeds
and lots of black pepper
I then put foil over them (aluminium) leave them in the oven for 30 minutes, and then cook them for the last 15/20 minutes uncovered. YUMMY my favourite!
Have you thought about some yummy salads? Thats a great way to get veggies in! You can make salads so pretty with loads of different vegetables mixed in, for example, celery, peppers, corn, beetroot, spinnach, rocket. You can be imaginative. I also put in seeds and I may put apples into the salad as well.
Also you can always make some soup (not too thick so its a main meal, as an appetiser) you can use so many different recipes as well. potato, leak, beans, celery, pepper, and just add whatever else you like. Its lovely in the winter and especially in the autumn (fall). All you have to do if you really want to disguise it is use a food processor. Make it totally liquidated and nobody will suspect a thing.
Good luck!
