Tropical Green Smoothie

I cannot find where I got this recipe on pinterest, so hopefully I don't forget anything, but it is quite tasty! A great way to quickly get in some veggies and fruit for the day!

1-2 cups spinach leaves
1 cup milk
1 cup frozen pineapple
1 cup frozen mango
1 banana
Agave, to taste
1 tsp vanilla
1/2 c berries, optional

Blend and serve!
