Nut, banana and coffee smoothie

So I had some almond milk at home and I have just come back from a nice walk. I decided I needed some energy so I came up with this recipe of an energy smoothie.

Ingredients
serves 1-2
1 frozen banana
1 tbsp nut butter (I used a mix of Brazil nuts, almonds and cashews)
1 small espresso shot
1 tbsp chia seeds
1 tsp vanilla extract
250 ml unsweetened almond milk

Put it all in a blender and mix until smooth.
