This is an easy one that my toddler loved! (That's him kissing the glass)
*disclaimer* I almost never measure, just eyeball everything!
•homemade raw kefir (substitute yogurt if necessary)
•hand full of fresh or frozen spinach
•one green apple sliced
•dash of cinnamon
•a tbs or so of raw honey or 100% maple syrup
throw it all in the blender and TA DA!!
