1 ripe mango, skinned, pitted, and chopped
1 Tablespoon chia seeds
1.5 cups frozen bananas
1 apple with skin, chopped
1/2 cup cold water
Process all ingredients in an immersion blender, makes a very thick smoothie — if you like a thinner smoothie, add 1/2 cup more water.
For normal blenders or food processors, replace apple with 1/2 cup apple juice.
