Here's something that will give you more empathy for your "picky" eater: kids aren't being difficult when they reject vegetables. They're biologically more sensitive to bitter flavors than adults are.
The very compounds that make vegetables healthy—especially leafy greens like kale—taste genuinely bitter to them.
But here's what professional chefs know: pairing bitter flavors with sweetness significantly reduces our perception of the bitterness.
Sweet + Bitter = Bitter
When we add enough sweetness, our brains literally can't detect the bitter compounds as strongly. The sweet flavor cancels it out. This is why a mixed berry smoothie with kale tastes like pure fruit—the natural sweetness of the berries completely masks the kale's bitterness.
I've made this smoothie in many cooking classes, and kids love it! No struggle, no convincing—just a delicious smoothie that happens to be packed with nutrients.

Chef Mark's cooking tool highlight: If you don't already own one, I highly recommend a high-powered blender. I use a Vitamix, and it's been worth every penny for 10+ years. It can handle any task and will last for literal decades.
A note on bagged kale: This is my ONLY recommended use for pre-chopped bagged kale. Chopped kale in a bag contains bits of stems, which isn't a problem when completely blended in a smoothie. But those stem pieces are very unpleasant in a salad, soup, or sauté. For everything else, buy whole kale—but for smoothies, bagged is super convenient and totally acceptable.
