There are lots of ways to make a smoothie- here's my take on a basic one. You can add any fruit and any fat(avocado, nuts, chia seeds, flax seeds) to change it up!
1 cup of almond/cashew milk
1 serving of protein powder
2 handfuls of spinach
1 fruit of your choice
serving of nuts or nut butter or avocado
add stevia or honey to desired sweetness
Put all ingredients in the blender and blend until smooth. Use frozen fruit for added thickness!
