What to keep in mind.

- 1Freeze your banana the night before for a thick, milkshake-like texture without ice cream.
- 2Rinse the canned white beans thoroughly to remove any metallic or salty taste.
- 3Blend the almond milk with the spinach first to ensure a smoother, greener puree before adding remaining ingredients.
- 4Taste after blending — if the smoothie is too thick, add a splash more almond milk and pulse briefly.
- 5Make ahead by portioning all dry ingredients (banana, beans, spinach) into a freezer bag; just add liquid when blending.

Why this is on our healthy list.
High in Fiber
White beans and spinach provide both soluble and insoluble fiber, supporting digestion and helping you feel full longer.
Plant-Based Protein
White beans and peanut butter add a modest but meaningful amount of plant protein, making this smoothie more balanced than a fruit-only version.
Rich in Iron
Spinach is a good source of non-heme iron; pairing it with a pinch of salt and vitamin C from the banana helps absorption.
Low in Added Sugar
With only a teaspoon of honey and no added syrups, the sweetness comes mostly from the banana, keeping added sugar minimal.
