Hidden Nutrition Raspberry Smoothie

I got some wonderful advice from a friend who was hiding vegetables from her kids. Put spinach in a fruit smoothie! I know, it sounds gross but TRY IT, it's great! My smoothies are always variable so these measurements are rough estimations, add amounts to your liking. 
Today's recipe:


1 banana
1 cup frozen raspberries
1 cup milk (add to get desired thickness)
1 handful of baby spinach
2-3 tablespoons of peanut butter


Add ingredients, blend, enjoy.
