I just hosted a dinner that was gluten-free, dairy-free, egg-free, and peanut-free that got EATEN. I am thrilled. And to think--I only had to do it once.
-grilled beets, carrots, [potatoes] w/sea salt and canola oil
-cornbread--could not find flax eggs, so these were gluten-free, but had egg :(
-fruit kabob bar w/optional readi whip (dairy) and sprinkles
-"Lucy's Sugar cookies" -- store bought, met the criteria. Quite good.
If you want your kid to try beets but they are reluctant, show them a "magic trick." Pop a beet into your mouth, chew chew chew (building a sense of mystery), then stick out your tongue. Gorgeous color! Some kids will consider the taste-risk worth the red tongue.
