I usually start my day with Auds declaring her hunger, immediately followed by can she watch TV and/or eat candy? The answer is usually a resounding NO but one thing she does get (and to this day still believes it belongs to the "treat" category) is a green popsicle (a.k.a. IcePop). Easy to make and delivers fruit and veg and other lovely ingredients. Making your own does let you control the sugar and other potential not-so-good fillers that come with store-bought smoothies.
The measurements below either fills up an icecube tray or a popsicle mold. Since the liquid is quite thick already, you can place toothpicks (I use three) in the centre without having to wait until the juice sets.
Here is a recipe for a kid's beginner smoothie/popsicle. Gradually over time I will add kale and other lovely greens.
Berry Fairy Popsicle
1 1/2 cups fresh pinapple juice
2 Ontario peaches
3 tbsp ground flax seed (Costco)
1 cup frozen organic blueberries (Costco)
1 cup local raspberries
1 cup 0% Greek yogurt
1 tbsp raw local honey
1 tbsp lemon juice, freshly squeezed
Blend, pour, freeze and enjoy!
