Could you try some different veggies, I do cucombers(uncooked), red peppers sliced, broccoli, I rarely serve cook veggies unless its in something. What about salad I do salads with lettuce, tomatoes,cucombers, red peppers and usually a vingeratte dressing this way the kids can kinda pick through and at least they will get some veggies. Maybe glazed carrots those are supper yummy. Do you ever do stirfrys those are a big hit here, rice with(hamburger or pork or chicken) fried with come kind of sauce onions, garlic, broccoli, carrots, celery, red peppers. I also serve smaller portions so that if they ask for more I tell them they have to finish what is on there plate.
