In blender, puree spinach, bananas, pineapple, water and vanilla until smooth.

Pour into six ice pop molds 1/3 cup each. Freeze 4-6 hours, or until firm.

Tips: For refreshing twist, add a few mint leaves before pureeing. If you don’t have ice pop molds, pour into two standard ice cube trays and insert wooden sticks after freezing about 1 hour.
