green smoothies or put greens in other smoothies (you can't see them in blueberry or chocolate smoothies. pb chocolate banana is a favorite around here).

You could check some of those sneaky chef books out from the library (I wouldn't lie to my kids about veggies, but those recipes make them palatable for kids so I like them).

if you bake you can do pumpkin muffins, zucchini bread, etc. I also like substituting pureed beans for some of the fat in recipes, but that's not strictly a veggie.

I finally figured out after many years that if I pureed the mushrooms with the sauce, my kids would eat stroganoff but they just didn't like mushroom pieces. Mushrooms are very nutritious so that's a good one.
