Homemade Shamrock Shake

Today being Sunday and it being the St.Patrick's day, I thought of making all things green. We had green eggs for breakfast, spinach rice for lunch and I made this Shamrock Shake as a dessert/drink. Shamrock Shake is a seasonal drink that McDonald's introduced to celebrate St.Patrick's Day. I have never tasted the real one but Aishwarya had and she thinks this is very close to the real one,though mintier and yummier by her standards.
Happy St.Patrick's Day!
