Line a baking sheet with parchment paper
Blend ½ cup of the Greek Yogurt in a blender with both bananas and the spinach until completely combined and smooth
Transfer mixture to a bowl and gently fold in the rest of the Greek yogurt. At this point, if you don’t think the mixture is thick enough, feel free to add more yogurt.
Transfer half of the mixture to a heavy duty gallon Ziploc bag (or piping bag if you have it).
Refrigerate the other half while you work.
Using a scissor, carefully snip a small hole in one corner of the bag. Gently squeeze the bag to pipe out your yogurt drops onto the baking sheet. I try to make mine big enough so she can pick them up with her fingers.
Once you’ve filled the baking sheet, transfer to freezer to set.
After about 2 hours, remove the baking sheet from the freezer and carefully (and quickly) remove the yogurt melts from the parchment paper and transfer them to a freezer storage bag.
