1 medium ripe banana,1 cup of fresh, canned, or frozen pineapple,3 large handfuls of fresh spinach (washed), 1 cup of plain Greek yogurt,6 oz. water, 1 teaspoon coconut oil (optional)
Put all ingredients in a blender, and blend until smooth.
If you want to add coconut oil, be sure it’s slightly melted when you add it so it emulsifies and blends well into the smoothie. Otherwise, it might be lumpy, especially if you are using frozen pineapple or if you add ice cubes.
If you use canned pineapple, you can add the juice, too, for a sweeter tasting smoothie.
