Pour 3/4 cup unsweetened almond milk (or your preferred milk) into a high-powered blender.
Add 1 scoop protein powder, 1/2 frozen banana, 1/2 cup frozen blueberries, 1 cup fresh spinach, and 1 tablespoon almond or peanut butter to the blender.
Blend on high until smooth and creamy, stopping to scrape the sides if needed.
If the mixture is too thick to blend, add more almond milk a little at a time until it blends smoothly.
Add ice as desired and blend again until you reach your preferred thickness.
Pour into a glass and enjoy immediately.
Notes
Use frozen fruit for a thicker, colder smoothie.
Adjust milk quantity to reach desired consistency.
Swap almond butter for peanut butter if preferred.
