Add all ingredients to a blender and blend until smooth.
Notes
Milk: We recommend cows milk for vegetarians. The protein content as well as other nutrients will be lower with almond, coconut, and oat milk.
Vegetarian/Pescatarian: Use a plant-based protein powder.
Spirulina: Spirulina is a nutrient-rich algae that's especially beneficial for vegetarians, offering plant-based protein, iron, and B vitamins—be sure to buy from a reputable brand that uses third-party testing. Read more in the spirulina and vegetarian notes.
