1 (14 ounce) can pineapple with juice (or frozen, but add some pineapple juice)
1/2 cup orange juice
1/4-1/2 cup coconut milk
1 banana, optional
ice, as desired
Place all the ingredients in the blender and mix. I usually put the ice in bit by bit because it blends better that way. Enjoy!
Source of recipe: I love pina coladas, but I no longer drink so here is my "virgin" version.
