I never really had to convince mine...they have no other choice, and they have been eating veggies since they were babies...I refuse to 'hide' food to get them to eat something...my 4 yo's favorite veggie is kale and my 2 yo loves raw carrots...they snack on veggies all the time...cherry tomatoes are their idea of a treat...
I hide them sometimes :) Deceptively Delicious is a great cookbook! Sometimes I just don't tell them what they are eating. Mashed cauliflower....YUM they think its mashed potatoes. They will eat them in soup if its chopped up finely. And sometimes they just won't eat what I fix, BUT they will take ONE thank you bite, and ONE no thank you bite. Our taste buds change every 7 years. And trying just a little you might find that you've been missing out on something awesome! I hated squash as a child, now its one of my favorite dishes!
Are you kidding? I serve them to him! Avacado was the first food he'd ever eaten. He's 5 now and people can't believe it when they see him eating brussells sprout, asparagus, brocalli, collard greens, you name it, he'll eat it. We're not picky. And we also got very lucky!
Add flavor (somehow) I used to make a spinach omelet/souffle........1/3 pound bacon cooked first, half dozen eggs and a can of Popeyes Spinach baked in a cast iron pan.....seasoned with Lowrys Seasoned Salt. Served 4. The flavor of bacon and eggs masked the spinach........of course, letting the kids know it was Popeyes seemed important, too. :o)
