I try to "hide" the veggies! One way is this: my kids adore pesto, so I give them artichoke tortellini smothered in pesto & grated parmesean cheese. The green of the pesto "hides" the green of the artichoke (or spinach) inside of the pasta. They don't care what's inside anymore because they cannot get enough of "pesto & pasta!" Or zucchini bread, carrot cake...
Second, we take a little bit of a hard line with them. It comes from two things: a great parenting book called "Parenting with love and logic" that promotes giving children of all ages choices, but needing to choose within the boundaries you give them( i.e., you may choose from options a,b,&c, but d,e,&f are acceptable because it was not one of the choices presented to you). And the second was hearing of how the MiL of a friend of mine cooks
FIVE different dinners every Sunday so everyone gets what they like to eat. Yikes!
When we're trying something new I always make sure that the main ingredient is something they love (shrimp, salmon, chicken), and add other stuff to it. And their favorite fruits. They have a choice of eating it or not, but they cannot leave the table without having at least three bites. If they refuse to eat anything, they will get it to eat the next meal. It's been a struggle at times, but they know we mean business and they've also learned that I won't fix something that they think is horrible (no brussel sprouts or liver & onions for them!). DS has some sensory issues, so that can get in the way. But you should see the things that they eat now! They love to help make and eat tilapia fish cakes, shrimp in tomatoes on cheesy grits, chicken satay, and lots of other goodies that I even like to eat!
I've found that Martha Stewart Everyday Food magazine is a godsend! The kids can look through it, find something they think looks good, and I'll cook it. The recipes are healthy & very simple to make, and there are many that you can make ahead and freeze.
But to get back to your other question, I've also found that trying to "hide" the veggies under cheese has the opposite effect. They want to know what they're eating. Sometimes they'll add salt & pepper or parmesean cheese (the kind in the green can), but otherwise they like their veggies plain.
Hope my jabbering helps
